[Platform_Windows]Windows-7: Firefox Window loses focus every time Flash plugin processes are (re-)launched

Description

Problem Description:
====================

Every time Firefox (re-)launches the three Flash plugin processes in Windows-7, the Firefox
window loses focus. Focus does not wander to any other non-Firefox window - no window in
the entire user environment has focus any more. The Firefox window must be explicitly mouse-
clicked to restore its focus after the three Flash plugin processes have been (re-)launched.

The three Flash plugin processes are: one process for "plugin-container.exe", and two processes
for "FlashPlayerPlugin_11_3_300_262.exe". These three processes are initially launched the first
time Firefox displays a web page with Flash content. When the user subsequently browses other
web pages without Flash content in such a way that 180 seconds elapse without any Flash content
being displayed in any tab in any Firefox window, then the three processes are terminated. The
next time the user visits a page with Flash content, the three processes are re-launched again.

This means that a user who slowly browses a variety of web pages with and without Flash content
can repeatedly lose Firefox window focus, namely each time the three processes are re-launched.

This problem occurs using Windows-7 SP1 (32-bit), Firefox 13.0.1, and Flash 11.3.300.262. See
"Any Workarounds" as to why this problem would seem to be a Flash issue and not a Firefox issue.



Steps to Reproduce:
===================

1. Start Firefox, and start Windows Task Manager in order to observe the Flash plugin processes.

2. Display any web page with Flash content, such as http://www.adobe.com/software/flash/about

3. The three Flash plugin processes (see above) should now be visible in Windows Task Manager.

4. Leave all web pages with Flash content (by going to www.google.com for example) so that no
Flash content is displayed in any tab in any Firefox window in the entire user environment.

5. Wait 180 seconds. The three Flash plugin processes should now disappear from Task Manager.
(Instead of waiting 180 seconds, it is sufficient to spend 180 seconds browsing web pages
which have no Flash content, which can of course happen with a real-world Firefox user. The
important thing is that 180 seconds must elapse without any Flash content being displayed in
any tab in any Firefox window, so that the three Flash plugin processes will be terminated.)

6. Return to any web page with Flash content, such as http://www.adobe.com/software/flash/about
This should cause the Firefox window to lose focus due to process re-launch, as described above.

7. Steps 3 through 6 can be repeated indefinitely, imitating an eclectic real-world Firefox user.



Actual Result:
==============

Windows-7: Firefox Window loses focus every time the Flash plugin processes are (re-)launched.



Expected Result:
================

Firefox window should NOT lose focus every time the Flash plugin processes are (re-)launched.



Any Workarounds:
================

    Still not fixed in new major version 13. I launched Firefox, loaded a web site, opened a new window, and went to YouTube. Flash made Firefox switch back to the other window. How can they not understand what a major problem this is?

    "Something else" could also mean "we know Flash is dead and pulled out the resources we'd need to actually fix the bug".

    But honestly: If you continue making Flashplayer user experience crappier and crappier with annoying bugs like this that will only speed up the process of people and pages shifting to HTML5 were possible.

    I'm already happy on most pages with Flashplayer turned off (by using Firefox's click to play). And I look forward to the few services that still need it to switch to something more appropriate with proper user support, so I can finally dispose of this buggy piece of software.

    It's an Adobe bug but it only affects Firefox. Mozilla won't/can't pay so bug won't be fixed.

  • AlexVallat

    12:13:49 AM GMT+00:00 Dec 9, 2013

    So is it that your developers are not competent to fix what should be a trivial issue, or that adobe simply don't care enough to even try? I guess "per priority" does point towards their utter indifference, but the mysterious "something else" could indicate that they tried and failed. Hard.

    I can't add another vote but I have to add even more annoyances this bug is causing:

    When navigating a menu (e.g. bookmarks in Firefox) while FlashPlayer is loading in background and stealing focus, the menu closes and one has to navigate to the correct position again after FlashPlayer is so kind and gives focus back.

  • Jing Yuan

    11:05:56 PM GMT+00:00 Jul 23, 2013

    Thanks all for your comments and vote.
    I am coordinating the issue info noted here to escalate it again to our management team.

    Before I get any conclusion to update to you all, I'd like you all who are impact by this issue continue vote this bug with comments noting how it impact your product/business. Thanks again!

    Here I'd like to share a workaround method for you that you can add "ProtectedMode=0" to the mms.cfg file to disable protectedmode to resolve the issue.

    Where to save mms.cfg, you can take reference from http://www.adobe.com/content/dam/Adobe/en/devnet/flash/articles/flash_player_admin_guide/flash_player_admin_guide.pdf

    Thanks very much for the technical details, AlexVallat. You'd think that was basic knowledge for a Windows GUI programmer. We're approaching the first anniversary, by the way.

    Maximus- I'm having the same problem. FF forum's best workaround is to disable Flash. It works but is a pain since if you want to see a video, you have to enable Flash, then refresh the page. Then go back and disable again. Seems like this should be something the genius programers at Adobe or FF could figure out. FF also has another plugin called Flash Block that works very well. Been using it for several years. Unfortunately, it doesn't seem to have any effect on this problem.

  • AlexVallat

    12:46:50 AM GMT+00:00 May 16, 2013

    I can't believe this is still not fixed. Look, this is not rocket science.

    1. Exit Firefox.
    2. Start new instance of Firefox with blank homepage (or at least one with no flash on it)
    3. Search Google for "http://www.adobe.com/software/flash/about/"
    4. Right click the first result and choose "Open in new window" (or shift-click it)
    5. Note how http://www.adobe.com/software/flash/about/ opens in a new foreground window, then focus is lost, and focus is returned to the first window, with the search results.

    This is obviously wrong and broken.

    Here are some diagnostics to help:
    If you look at a log of the windows which get focus, you can see that the sequence is:

    1. New window gets focus
    2. That window loads the Flash Player page content
    3. A window with the class name "Edit" from the process "C:\Windows\SysWOW64\Macromed\Flash\FlashPlayerPlugin_11_7_700_202.exe" gets focus
    4. The Flash Player page window gets focus
    5. The Google Search page window gets focus

    And here is some info to help your developers:

    To ShowWindow without giving focus, pass the command SW_SHOWNOACTIVATE
    The first call to ShowWindow uses may use the STARTUPINFO structure, so you can include in dwFlags STARTF_USESHOWWINDOW, then in wShowWindow include SW_SHOWNOACTIVATE
    To call SetWindowPos without giving focus, include the flag SWP_NOACTIVATE

    What I'm getting at here is that the solution is not ever more cunning ways to try and return focus to the correct window correctly, the solution is *not to take focus in the first place*

    Activating click-to-play in Firefox is another possibility to gain more control over the stupid flash-plugin. If you use it right.

    That means, you should'nt allow click-to-play to have flash activated for specific websites. If you do, you can't control the timing of the focus-loss exactly.

    Con:
    - You have to click each time you want to use flash.

    Pros:
    - Focus-loss can only occur right after you click-to-play.
    - Any flash content is disabled by default. That means, there should be no danger of infection or performance-impairment by flash elements which you don't need to run.

    Since Adobe is ratting all the victims of their lousy piece of software out and can't ever be excpected to come around, I have something that might help all you guys who are racked with this terrible bug:

    There is a Firefox-Addon called "FlashDisable". It allows you to directly activate or deactivate the Flash plugin. So you can use the current version of flash and reduce the negative impacts of this bug.

    You still have to be careful not to type or click anything when the flash processes launch. But with this addon, at least you have more control over the timing.

    "State: Closed
    Status: Deferred"

    Adobe's statement:
    "If bug is set as ToTrack or Closed as Defer, it means we have reproduced the problem, but unfortunately, it does not get high enough priority to address in our current release."

    In other words:
    "We know about the problem, but we seriously don't give a shit about you or any other user's problems caused by our miserable product."

    They only care about short-term profits, which is short-sighted and stupid considering that it's their own customers which they are hurting with this behavior. But what are you gonna do? That's how they are.

    In conclusion: Nothing has changed.

  • Quatrix0

    9:25:07 AM GMT+00:00 Feb 5, 2013

    Can we get some kind of confirmation that Adobe is working on this as a priority? It's been almost 8 months now. Every time I open a new Firefox window and load a page that uses Flash, it switches back to the previous window. I guess their hack (which they were calling a fix) mistakenly assumes all Firefox users use tabs and never have more than one window open. Even with a single window there's still a flicker that's unnecessary and unacceptable. This is ridiculous.

  • Quatrix0

    2:10:40 PM GMT+00:00 Jan 9, 2013

    This is basic GUI programming knowledge. All kinds of Windows processes start up in the background without affecting any part of the GUI. There's no reason that this can't do the same thing. In fact, Firefox's own plugin container does just that.

  • Maximus1337

    7:13:28 PM GMT+00:00 Jan 8, 2013

    Jing Chen:
    "Firefox will flicker [...] in the task bar [...]"

    That's the problem.
    That has been the problem for over 6 months now.

    I don't give a damn, how long FF loses focus. The focus should'nt change AT ALL! Not even for a millisecond!

    There are various scenarios where you need FF NOT TO LOSE FOCUS AT ALL, for example whenever you need a button pressed without interruption.

    Hi,

    Regards to loose letters impact, developer has created a test html page that redirects to a page with a SWF in 5 seconds. But we didn't see it happens.
    Method to simulate:
    1. goto a page with a textfield like google.com
    2. open redirect.html in another tab
    3. go back to google.com and type in a sentence for 5 seconds. Observe if any letters were missed.

    This is the test results:
    - Firefox will flicker the focus shown in the task bar, but automatically regains focus
    - Although it paused for less than 0.5 secs, I was still able to type in my sentence without letters missing.

    It's appreciate that you could test this page and post back the result together with your test environment(machine). Thank you very much.

    Regards,

    Jing

    Thanks to all who have commented, I was able to hack together a kludge that was good enough for my purposes.

    // append a div to the end of the page
    var _div = document.createElement('div');
    _div.style.visibility = 'hidden';
    var _body = document.getElementsByTagName('body')[0];
    _body.appendChild(_div);

    // Firefox launches flash in sandbox and loses focus
    // by creating a temporary flash object, the sandbox is created
    _div.innerHTML = '<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="0" height="0"
    etc...
    // provide a non-existent file
    <param name="movie" value="dummy.swf">

    // launch your real flash application
    your code goes here

    // remove the temporary flash object
    _body.removeChild(_div);

    For bulk processing, place the code in a javascript function and using the document onload event fire another function that establishes an onclick handler to the relevant links in your page that calls the above kludge. Instead of putting your code in the above kludge, simply return true and your regular event should fire just fine.

    Cheers

    In a few days this bug will have hurt millions of users (most of whom have no idea that it's actually flash and blame their hardware, firefox, Windows or whatever) for HALF A YEAR!

    How anyone, including and especially Bob-Hill, still can't see the incompetence and ignorance with which we're dealing here, is baffling to me.

    One should definitely alert the public and the press to this embarrassing issue.

    Hi Jing,

    As far as I am aware, there are two problems still to be addressed in this issue:

    1. The "blink" problem, as described in various "Notes" from Aug 15 until Aug 21.

    2. The fact that after losing focus, Flash sometimes restores focus to the wrong
    window. Many thanks to Quatrix0 for posting this in his "Note" at 4:22:47 PM
    PDT on Aug 25. This problem is of course confusing and/or annoying for users.

    Both these problems would be eliminated if Flash did not lose focus in the first
    place. Interestingly Firefox itself does not lose focus at all when it launches
    the process for "plugin-container.exe". Could you please ask your developers the
    following question, and then post their response as another "Note" into this bug?

    "Given that Firefox itself does not lose focus at all when it launches a process
    for "plugin-container.exe", should it not also be technically possible for the
    Flash plugin to entirely avoid losing focus when launching the processes for
    "FlashPlayerPlugin_11_5_502_135.exe"? If this is not possible, why not?"

    With many thanks for your help,

    and kind regards,

    Bob

    Correction and Update: I had forgotten that Protected Mode is enabled by default without showing the third command line for it, only the two for Autoupdat=1 and Silentupdate=1.
    When I remembered and added the correct command line to disable it - ProtectedMode=0 - the focus issue was partially fixed - only a single click on the page brought the scrolling back again after pausing a YouTube video, but that shouldn't be necessary either. And that defeats the purpose of Protected Mode, but at least it does seem to have to do with Protected Mode.

    But the fact that you still have to click on the page shows something else is going on here as well.

    Hi Bob,
    I posted a bug report about loss of focus issues on Nov. 27, which was just officially "Withdrawn"and "Closed" as a duplicate of yours. I don't think it's a duplicate, but I also don't fully understand your description. You won't be able to see mine, since it was "Withdrawn", so I pasted the much of the report.

    If mine is a dup of yours... fine. I notice you're not responding to anyone on your own report except Jing - I guess I shouldn't expect any either. Anyone else....please let me know what you think. Protected Mode is NOT the problem. That's the first thing I tested for, and it happens in 10.3 without Protected Mode, and I can't even find Protected Mode in the 11.5 in the mms file, as it was in 11.3 and 11.4.
    Sorry for taking up so much room, but Adobe isn't explaining anything - maybe you can.
    Thanks to anyone who responds, CheckMate

    Adobe Flash Player 11.5 - Bug 3372854
    Created on Tuesday, November 27, 2012
    Title
    [Platform_Windows]Pausing YouTube Videos disables scrolling on the page with Firefox.
    Description

    Problem Description:When you play a video on YouTube and either pause the video or change the quality ( resolution), or even click Replay, the page scrolling no longer responds. This has been going on since version 11.4, and happens even with the 10.3 version.

    Steps to Reproduce:Start playing any video on YouTube. Pause the video, or click on "change quality" and click on another resolution, or simply click Replay.

    Actual Result:

    1. Start any video on YouTube and then pause the video to let it buffer, or click on "Change Quality" to change the resolution, or click on the Replay button.

    2. Try to scroll on the page - it doesn't respond. Clicking on the page doesn't enable it.This also happens when I click on ANYTHING in the video.

    3. Uninstall Adobe Flash 11.5 , then reinstall 10.3. Scrolling also doesn't respond although clicking on the page enables scrolling again.

    4 Testing with Internet Explorer 9 and Chrome 23 does not reproduce this issue - I don't ever have to click on the page to continue scrolling with the other browsers

    5. Opt into the YouTube HTML5 Trial Video Player to test whether this is exclusively a Flash issue.http://www.youtube.com/html5. Then click on "Join The HTML5 Trial". Then start a video and right click on it . If a video is a .webm, after right clicking on it, it will read "About HTML5" on the bottom of the menu.
    Pausing the .webm video and then trying to scroll works without having to click on anything else first. Clicking on anything in the video does not reproduce this issue with the .webm format.

    6. Copy the url the test .webm video , then click on "About HTML5", then click on "Leave the HTML5 Trial". The same video is now an .flv.

    7. Paste the url of the video into Firefox and play the video. The video is now a .flv video and the issue reproduces. A test video I used which is available as an HTML5 .webm is http://www.youtube.com/watch?v=1mXFVoX8INQ.

    8. Testing with the most recent Firefox Nightly build version 20.0a1(2012-1-25) in Safe Mode reproduces the issue.


    Expected Result:
    1. Start to play any video on YouTube.
    2. Pause the video and scroll on the page.
    3. Scrolling on the page should respond without clicking on anything else first.

    Any Workarounds: Yes.
    1.Click on the Desktop and then click on the page ot re enable the scrollling. With the 10.3, clicking on the page alone works.
    2. Sometimes, clicking on the page once or twice works with the 11.5.
    3. Click on another tab and back again.
    4. Opt into the YouTube HTML5 Trial. This issue does NOT reproduce with the .webm file format. This proves it's a Flash issue and not just a Firefox or touch pad issue. The downside is that most videos are not yet in .webm format.

    That is an interesting theory.

    There's a reason this isn't getting fixed. It's simple really. Adobe WANTS the Flash app(s) to force the browser to loose focus. Then you have to click on the page to regain focus, increasing the chances that you will click on a banner ad. This issue has been going on for a very long time. I first noticed years ago but here lately it is become chronic. Sites like NFL.com are absolutely horrible. Sites like that reload, lose focus, redirect, refresh, over and over and over and over. There's a very good reason for this: greed. Get a group of billionaires together and they'll come up with all sorts of nastiness. So, factor greed into the equation and you may not get a solution - but you can become wiser. I suggest steering clear of cluttered and clunky websites that are Flash heavy, and those that constantly use annoying redirects and reloads and refreshes. Am I paranoid? Naw. I'm in the business. I know how executives think. They are greedy, shifty and don't care one whit about the end user, only about how many clicks, how many visits, how big is the bottom line. Peace.

    This is still occuring on one of our Flex apps - works fine in older versions of Flash and on IE with older version of Flash

    Currently using 11.4.402.265

    11.4.402.278: Still partial fix(FF loses focus for a moment then regains it when Flash processes launch).

    Focus "snagging" bug(eg. Youtube player still holding the cursor despite clicking outside the page) NOW seems to be fixed with this version's advent!

    From that disturbing post, I think it is safe to deduce that the developer obviously still has not the slightest clue how this severe bug affects everything.

    Maybe they should be looking for a different kind of work. Because even no development at all is much better than letting the users do all the work and even so being unable to recognize this problem. It's no rocket science. Yet, AFTER ALMOST 3 MONTHS, they still are not getting it!

    You want us to vote AGAIN? What for? The problem is not fixed! Votes obviously don't change anything!

    This charade has grown too sad and too embarrassing to even comment on it any more.

    Just leave the users in peace and terminate the support altogether, leaving 11.2 as the last official release.
    Evidently, Flash is dead.

  • Jing Chen

    4:18:56 AM GMT+00:00 Sep 10, 2012

    I've contact the developer, and they want me to triage the votes after the update of 11.4, please give votes to this issue if it impacts your work and development.

  • Maximus1337

    12:06:04 PM GMT+00:00 Sep 7, 2012

    You would have us deactivate the protected mode and therefore the sandbox, right?
    That would be a work-around, not a fix.

    Also, I suppose it would be easier to just install Flash 11.2 as Firefox Plugin.
    That's what I did (as I mentioned earlier) and it works just fine. Using Flash is very dangerous anyway, so I decided to stop bothering with Adobe's crappy updates.

    OK. I've watched this long enough that I've had it with the lack of help from Adobe. I've fixed this issue for myself about a month or so ago and I haven't had any issues with losing focus ever since.

    The problem is the new Flash Protected mode which has been implemented as default for firefox. If you want to get rid of this issue, follow the very simple instructions set out in the following website like I did and be done with it. Then it will be, how do you say, 'Fixed'.

  • Quatrix0

    12:51:39 PM GMT+00:00 Aug 28, 2012

  • Quatrix0

    4:22:47 PM GMT+00:00 Aug 25, 2012

    There's a more serious problem. When I open a new Firefox window and open a page that uses Flash, focus goes back to the first window.

  • Quatrix0

    7:06:51 AM GMT+00:00 Aug 24, 2012

    With all due respect, your developers MUST know that what they did is a partial hack and shouldn't need any additional explanation from Bob-Hill. Maybe they have plans for a real fix in a future version, or maybe they just thought no one would notice the incomplete fix. The more disturbing alternative is that they don't understand window focus, which is a fundamental aspect of GUI programming.

  • Maximus1337

    Hi Jing,

    In the first paragraph of my previous note, after right-clicking on the Windows 7
    Taskbar, CLICK ON "PROPERTIES", and then set "Taskbar buttons" to "Never combine".

    With apologies for the confusion,

    and kind regards,

    Bob

  • Bob-Hill

    1:16:02 PM GMT+00:00 Aug 21, 2012

    Hi Jing,

    If not already the case, it should be easier to observe the focus-loss/regain-gap
    by right-clicking on the Windows 7 Taskbar and then setting the Windows 7 Taskbar
    buttons to "Never combine", so that each individual window has its own wide button
    in the taskbar. It is then very easy to see exactly which window has focus at any
    point in time - its button in the taskbar is a different colour to all the others.

    The focus-loss/regain-gap can then be reproduced (now using Flash 11.4.402.265) as follows:

    1. Start Firefox, and start Windows Task Manager in order to observe the Flash plugin processes.

    2. Display any web page with Flash content, such as http://www.adobe.com/software/flash/about

    3. The three Flash plugin processes (one process for "plugin-container.exe" and two processes
    for "FlashPlayerPlugin_11_4_402_265.exe") should now be visible in Windows Task Manager.

    4. Leave all web pages with Flash content (by going to www.google.com for example) so that no
    Flash content is displayed in any tab in any Firefox window in the entire user environment.

    5. Wait 180 seconds. The three Flash plugin processes should now disappear from Task Manager.
    (Instead of waiting 180 seconds, it is sufficient to spend 180 seconds browsing web pages
    which have no Flash content, which can of course happen with a real-world Firefox user. The
    important thing is that 180 seconds must elapse without any Flash content being displayed in
    any tab in any Firefox window, so that the three Flash plugin processes will be terminated.)

    6. Now it is necessary to watch Firefox's Task button in the Windows 7 Taskbar very carefully!!!
    Return to any web page with Flash content, such as http://www.adobe.com/software/flash/about
    This should cause the Firefox window to lose and regain focus quite quickly, as demonstrated
    by Firefox's Task button in the Windows 7 Taskbar blinking to "non-focus" and then to "focus".

    7. Steps 3 through 6 can be repeated indefinitely, imitating an eclectic real-world Firefox user.

    With many thanks for your help,

    and kind regards,

    Bob

    I updated to 11.4 today, and the alleviated (but still present) problem is obvious. The Firefox item on the Windows 7 task bar loses its highlight for maybe half a second and then regains focus. Two months and a few Flash versions later, and all we have is a hack.

    Hi Bob,

    Thank you very much for your detailed and clear info.
    I try reproducing the gap, but I didn't see it, I kept scrolling the mouse in the process of Firefox's starting, and once it starts, it's rotatable, and the icon is still highlighted. Is there any other method to reproduce this issue?

    Thank you again for your support.

    Hello Jing,

    Thank you for contacting the developers about focus loss/regain in Flash 11.4.400.252.

    The impact of the gap between focus loss and regain was described by SearinoxNavras
    in his Note at 7:42:08 AM PDT Aug 15, 2012. This focus-loss/regain-gap can actually
    have a more insidious impact than total loss of focus, because a user typing text
    into a chatroom (for example) will definitely become aware of a total loss of focus
    and take steps to re-type the lost keystrokes, whereas a user might not even be aware
    of a half-second focus-loss/regain-gap and may not re-type the lost keystrokes at all.

    With many thanks for your help,

    and kind regards,

    Bob

    5:35:52 PM GMT+00:00 Aug 17, 2012

    Hello Jing Chen,

    Thank you for starting to address this problem in Flash Version 11.4.

    I have tested Flash Beta 11.4.400.252, and got the same results as
    SearinoxNavras (please see his Note at 7:42:08 AM PDT Aug 15, 2012).

    It would appear that the Flash plugin still causes the Firefox window
    to lose focus when the Flash plugin launches the two processes for
    "FlashPlayerPlugin_11_4_400_252.exe", but that the plugin now somehow
    restores focus to the Firefox window after the processes are launched.

    As SearinoxNavras states in his Note, it would be much better if these
    two processes for "FlashPlayerPlugin_11_4_400_252.exe" could be launched
    without the Firefox window losing its focus at all. When Firefox itself
    first launches the process for "plugin-container.exe", the Firefox window
    does not lose focus even for a fraction of a second, which implies that
    there must be some way to launch a process in Windows without losing focus.

    With many thanks for your help,

    and kind regards,

    Bob Hill

    Another addition about Protected Mode focus: on sites like YouTube it's no longer as easy as clicking on a random part of the vid page to get the cursor unstuck from Flash. It stays inside flash until you click a javascript element like the comment box or thumbs up/down. This ONLY happens in protected mode.

    Flash Player has already had an annoying focus monopoly in Firefox. If you click a Flash element, your tabbing only swaps between parts of that element and you can't get out of it without using your mouse to click away. NOW IT'S EVEN WORSE!

  • Maximus1337

    8:48:03 AM GMT+00:00 Aug 15, 2012

    This whole thing is such a disgrace for Adobe and Flash...it's almost getting funny by now.

    I guess, if I am gonna decide to need Flash again (just because many content providers are'nt able enough to replace Flash with one of the much better alternatives), I'm just gonna use an older version.

    No losing focus, no poorly designed sandbox...security and flash are mutually exclusive anyway, so why bother?

  • SearinoxNavras

    7:42:08 AM GMT+00:00 Aug 15, 2012

    I checked out the 11.4 beta. Guys seriously, give this a PROPER fix! When you open a Flash tab and the processes launch, Firefox loses focus for about a second before it regains it.

    Yes, it DOES regain focus on its own now, but it STILL loses it for about half a second. If a tab's reloading in the background, you open it without focusing it like with mid mouse button, and you're typing, you WILL end up skipping text for that period that it takes for the plugin to give FF back its focus.

    Consider now that the plugin closes itself after being idle and you can get some scenarios where it's really messing up people's browsing, for example typing in web-based chatrooms while mid-mouse opening links being posted there.

    PLEASE give this a PROPER fix where there is ZERO loss of focus in the first place!

    No, I have'nt tried the beta.
    Knowing that you are unable to release final versions without SEVERE bugs, installing a beta would seem to be moronic begavior.

    "can't give a release to every fixed issue"
    Really? Not even within more than two weeks? Not even with a bug this big and annoying?
    Well, thanks for making my point.

    Even more irritating than the bug itself (since the solution is simply to deactivate your foul piece of software, which is btw absolutely rewarding, because you'll get a faster and safer browsing experience with less spam) is the fact that you people don't see the contradiction in declaring something as fixed without actually having released any fixed version.

    Imagine a car-manufacturer who builds cars that would randomly explode after about 10k miles saying "I don't know what you people are complaining about. So thousands of people are dying across the globe because my cars are exploding? Well tough luck. I already FIXED the problem by building a prototype which does'nt explode. It's right there in my garage! Your cars can't be repaired yet and therefore thousand of people are going to continue to die in the next couple of weeks, but it is safe to say that the problem is completely FIXED. So actually there is no problem. Yay!"

    See the contradiction now?

    I'm adding a vote for this because since the last Flash update, anytime I click on a Flash object in a page, I can't get keyboard focus back to the main page. If I want to close the tab for instance, I have to click the 'x' for the tab. Previously, I could click anywhere in the window outside the Flash object to return focus to the Firefox Window.

    (Using Firefox 14.0.1 on Windows 7 x64)

    I (and others I know) are experiencing this issue too. Using accessibility tools, I have determined that focus goes to an invisible, top level Windows edit control (window class name: "Edit") owned by the sandboxed Flash process (flashplayerplugin_11_3_300_265.exe). Interestingly, you can actually type into, read and edit the text in this control, though it doesn't achieve anything. It is an incredibly annoying bug.

    It's cumbersome to even type an email when the focus is gone while typing away. Even reading through this page, Firefox lost focus multiple times. Not to mention, Firefox stalls every so often, too.

I'm not really sure I understand what you mean by it's not important enough to be escalated, but maybe if enough peoplelike me (I joined this Adobe "site" just to chime in here because frankly my very way of life is being compromised - sounds dramatic, but 6-7 crashes per day is a impactful and makes one very on edge just doing their usual work because at any minute it can crash again.)

    oops, I see it has been escalated - thank you - and I understand what you mean by losing focus - very interesting. This happens to me when I say stalling; it's not really stalling; it's like a "shift" away from where it should be - forgive my lack of technical language. But for me, the really unworkable problem is the eventual crash and shutting down of Firefox all together, apparently due to that new "application window" that appears at the bottom of the screen, called adobe flash player 11_3_300_262.exe

    Hello Jing,

    Thank you for your quick response. There are two ways to tell whether the window is out of focus.

    Firstly, in the Windows 7 taskbar, the taskbar button for Firefox loses its brightness compared to
    all the other buttons - all the taskbar buttons become equally dull, because no window anywhere
    has focus. (Unfortunately, your attachment "test.jpg" does not include the Windows 7 taskbar.)

    Secondly, moving the mouse wheel no longer causes the Firefox window contents to scroll up or down.

    May I ask if it is possible that you might be using a 64-bit version of Windows 7? I have reported
    this problem against 32-bit Windows 7, and I do not have a 64-bit Windows system at my disposal. If
    your testing was on a 64-bit system, may I kindly ask you to try the test again on a 32-bit system?

    Please also note that other people seem to have this problem, but without official Adobe Flash bugs:

    https://bugzilla.mozilla.org/show_bug.cgi?id=747683#c46

    http://forums.adobe.com/message/4479324 (Please find several occurrences of the word "focus" in

    Any Workarounds:
    ================

    This entire problem can be circumvented by disabling Flash "Protected Mode", as described else-
    where around the Internet. This however completely negates the entire Flash sandbox facility,
    which is highly undesirable from a security point of view. Without Protected Mode, Firefox
    still launches one process for "plugin-container.exe" for the Flash plugin, and that process
    is still terminated 180 seconds after ceasing to be used, and will be re-launched for any
    further Flash content, as described above. However, the launch and later repeated re-launches
    of single processes just for "plugin-container.exe" do NOT cause the Firefox window to lose
    focus - the Firefox window only loses focus in Flash Protected Mode, when the additional two
    processes for "FlashPlayerPlugin_11_3_300_262.exe" are launched/re-launched. For this reason
    it would seem that the loss of focus is more likely a Flash issue, rather than a Firefox issue.

    The repetitive aspect of this problem (losing focus on each re-launch of the three processes)
    can be circumvented by always keeping a web page with Flash content open in any tab of any
    Firefox window in the entire user environment. Keeping such a tab permanently open prevents
    the three Flash plugin processes from being terminated 180 seconds after ceasing to be used,
    because the processes never cease being used. This way the three processes never need to be
    re-launched, and so no Firefox window ever loses focus on any subsequent Flash content display.

    This bug impacts or flash live video solution by beeing a nuisance to our customers. No wonder people start to move away from flash, as even such visible and highly disruptive bugs do not get any attention from Adobe at all.

    In several labs we have software that launches a window with flash in it for taking a test from, the window immediately is minimized upon launching, requiring the students to reopen the test from the taskbar every time they come in to take a test. It is confusing for the students the first time it occurs to them and requires us to have to explain that that happens to each student.

    We are developing edu application. In some scenarios instructor can review the students' progress by opening variety of new popup windows which includes among other flash content too (charts, video, animations). We get frequently reported by support team and users that newly opened window is hidden right away. First I have suspected that it is FF bug and reported in their bug database only to find the problem lies elsewhere.

    I think the focus is given back to the wrong window.

    I can disable protected mode in my flash plugin. I am sure I cannot require this from our users and I doubt that they are enough technically skilled to fix that themselves.

    Few of our developers have tried html5 edge should we prepare ourselves for waiting on easy fixes for years there too?

    Thanks,

    Having newly loaded web pages (newly launched Firefox windows) seemingly randomly pop behind the window from which they were originally launched is maddening, especially as this Adobe Flash Player bug has been in existence without a fix for at least a year by now.

    There’s an excellent page describing the problem in more technical detail here: http://www.ghacks.net/2012/08/20/flash-bug-firefox-losing-focus-when-flash-contents-are-loaded/

    There’s also a Bugzilla@Mozilla report on the same issue here:

    I have been able to reproduce this issue in windows 8 as well as windows 7. Since the window is re-focused to another browsers, customers are not staying on my page. As such, if this is not addressed, I will need to move away from using flash and will instruct my customers to do the same.

    Every time I open a link in a new window, if the page uses flash it disappears behind the old window. This is extremely frustrating.

    Whilst my preferred solution is to avoid sites which use Flash, this is not always possible. Therefore it would be nice if you managed to do what every other windows GUI application in the world does, and handle window focus appropriately.

    Dito.
    I was using 11.2.202.235 (AFAIK the last one that actually worked without this incredibly stupid bug) until a few weeks ago, when it bacame public that in every Flash version but the current one would be critical Zero Day risks.

    So for a few weeks now, I am completely without flash. Many things are better (for example HTML5 and webm instead of that flash-crap) now. The only impairment is some videos on youtube which stopped working.
    For that, I blame Google. They should stop using flash altogether and ASAP, as everyone should.

    The only thing worse than Flash, is Java. xD

    I always have firefox in background with 10 or more tabs, now i can`t watch movie or play fullscreen game because every 3-5 minutes it lost focus and go out of fullscreen mode (movieplayer) and game window minimized in this situation.

    I've experienced this bug numerous times with Flash and Firefox. It most often occurs when I open a link in a new window. If the new window contains flash sometimes focus shifts back to the original window. It's very frustrating and difficult to browse web pages like this. This problem has been around for months, but I thought for sure it would have been fixed by now. I'm astonished that it isn't as it is significantly impacting my work.

    Once I clikc on flash, shortcut keys and mousescrolls don't work until I click somewhere else on the webpage.
    I don't see the point of Flash needing any focus. Just let it not!

    Firefox should not loose windows focus when the flash player is activated.

    Every time I pause a YouTube video or change the resolution, page scrolling is disabled. Disabling Protected Mode only simplifies the workaround to having to click on the page to reenable it, which is still annoying, and defeats the purpose of Protected Mode. This has been going on for six months and is not reproducing with IE9 or Chrome 23.

    It hurts my productivity by wasting my time with extra clicks, checking for updates or any other workarounds. This fix is taking entirely too long and productivity is not just limited to the work environment -personal use loss of productivity is just as important.

    The way windows react is crucial to a efficient and predictive working flow. Switching back to a window you're working in every time the flash plugin stats is very, very annoying. It really hurts my working routine and it also hurts Firefox, as most people wont recognise this is a Flash problem.

    The Firefox screen(s) minimize(s) suddenly in the midst of work. I can then do nothing for between 30 and 60 seconds. This is a waste of time and extremely irritating. I will try to find an alternative to Flash if you are not bothering to fix this bug.

    Adobe, the issue is not "fixed". Firefox is still losing focus as of your last update.

    This is supremely annoying and is not a minor issue, certainly not when it negatively impacts browsing every minute or so.

  • Quatrix0

    11:17:07 AM GMT+00:00 Aug 21, 2012

    Better but still not fixed in 11.4. The split-second loss of focus interrupts typing, and now a background Firefox window sometimes STEALS focus due to Flash.

    It is a pain to wait a few seconds and have the firefox window which was just opened lose focus. The only good work around is to disable the flash player add on in firefox. Adobe needs to fix this bug!!!

  • cgeorge800

    6:53:39 AM GMT+00:00 Jul 28, 2012

    Because the Firefox window often loses focus, I must frequently Alt + Tab back to or click back into the window to regain focus. Otherwise, I can't scroll with the mouse wheel, keyboard arrow keys, can't use Page Up, Page Down keys, Tab through elements in the page, etc., etc., etc. Sometimes this happens in the middle of typing in a text field on a web page, so that gets interrupted. All VERY annoying.

  • thescandalon

    7:22:28 AM GMT+00:00 Jul 26, 2012

    Also experiencing this issue. While a mouse click or alt-tab works to restore window focus, it's quite disruptive to browser workflow. It has changed a basic and fundamental operation behavior. In my opinion, nothing (especially within a browser) should be able to change window focus without explicit user permission.

    Every time the Flash processes launch, focus is lost and I have to alt+tab out of and back into Firefox. It is even more problematic for screen reader users such as myself because when focus is lost, we can no longer read the page at all until focus is restored.

  • Marc Durdin

    5:02:25 PM GMT+00:00 Jul 23, 2012

    As per other comments, losing focus any time a flash-enabled page loads is a constant timewaster. Annoyances like these are catalysts for users to examine how much they actually need a platform, so I suggest Adobe get on top of it as quickly as possible!

  • KLS1000

    11:20:53 AM GMT+00:00 Jul 22, 2012

    It is annoying to have to keep clicking on a screen in order to keep typing an email or scrolling information. It is also very detrimental to minimizing use of the mouse for those with repetitive stress tendencies. I do a lot of emailing for work and when I am signed on through Remote Desktop I can barely type a sentence without having to re-click over and over again. It's nearly enough to make me go back to using the postal service!

    Just another reason for me to hate flash. It's outdated, unsafe, unstable, slow and adobe is not even professinal enough to either avoid such a grave bug or to fix it in time.

  • stgrusso

    5:41:21 AM GMT+00:00 Jul 21, 2012

    Firefox is losing focus regularly during normal use. Can reproduce the issue per Bob-Hill's instructions, and have also been experiencing a defocus while using applications other than Firefox on occasion (when Firefox is running in the background), though I haven't been able to reproduce this.

    This is the most annoying bug that hit me in Firefox for a very very long time.

    To only mention two cases were repeatedly loosing focus easily leads to uncontrollable rage:

    1. Just browse a page with flash content and start scrolling (e.g. the most basic functionality every web browser should offer). Since Flash content is loading damn slow in most cases you won't notice anything for a few seconds but as soon as the flash content is loaded Firefox looses focus and you can't even scroll in the page!

    2. Open a new background tab to let it load in background (as I do all the time... why waste my precious time with waiting for a tab to load?). Continue with your work in the foreground tab (e.g. open context menu to complete some tasks). But as soon as the background tab includes flash content Firefox will lose focus. Context menu closes and your work in the foreground tab is shamelessly interrupted.

    If that's the way development of Flashplayer continues I'd say: Goodbye Flash, Hello HTML5!
    I'd anticipated a fix for such a gross error within less than a week (not to mention how it was possible for such a bug to get through quality control in the first place).

    Can't load videos in Firefox. Was only able to load flashplayer properly through Opera which can utilize it properly. Firefox then worked once with flash, then failed again. This is a new W7x64 machine. Never had a problem in this regard with XP desktop, or Vista laptop.

  • circleville

    2:14:31 PM GMT+00:00 Jul 4, 2012

    Sometimes occurs when I'm in the middle of typing something, which ratchets the level of irritation upward in a rather hyperbolic ascent path that's typically accompanied by a whompload of exceedingly profane language!

    Note: Still occurs following the update to v11.3.100.265 (Win7 Pro x64), and seems to be even more frequent (AND annoying!).

  • Mal Reynolds

    11:49:13 PM GMT+00:00 Jun 29, 2012

    It's annoying. Incredibly annoying. When you are typing input into a window, best case you suddenly start hearing "ba-doing!-ba-doing!-ba-doing!" and find that you're typing into empty space, then have to re-type the missing original content. Worst case you lose important content in the form/document/e-mail/whatever it is that you're typing. This is an unacceptable bug, pure and simple. It interferes with you being able to use your computer to access and interact with a web site. That is NOT (cheezes, it just happened again) NOT, I repeat, what would be expected from a professionally compiled computer program.

    A very excellent Problem Description. Like many others, I too have this problem. So I vote for myself and on behalf of all others, who are unaware of this bug report, to ratchet up the priority of this bug. Thanks to Bob Hill, I simply open a tab with Flash content and leave it open. It works for me.

    12:30:07 PM GMT+00:00 Jun 28, 2012

    Extremely annoying. Firefox always had problems with the tab selection in flash, and this just took it to a whole new level of worse. Having to reselect the browser when opening flash can lead to accidental program launching or closing since you're still pressing keyboard shortcuts and think you're in the browser. I can't list how many things are wrong with focus loss.

  • mikenicholls

    8:10:45 PM GMT+00:00 Jun 27, 2012

    Seriously interferes with browsing by stealing focus from the browser, rendering both keyboard shortcuts and the mouse scrollwheel unusable. I regularly Firefox with Flash Player 11.3 on three different Windows 7 machines and this is an issue on all of them.

    Flash 11,3,300,262. installed
    Hardware acceleration--off for both Firefox and Flash Player
    Windows on my system is set to display in "classic mode."
    -------------------------------------------------------------------------------------------
    While I've never timed it, I DID notice that the two flash player files disappear from task manager after exiting a site with Flash content, and spending some time there. Then, when I switch back to another site, with Flash content, and the appropriate plugins are loaded, Firefox loses focus again.

    Hello. Same thing happens here with Windows 7 Pro/SP1 64-bit, FF 13.0.1 and Flash 11.3.300.262 when Protected Mode is on. It's kind of annoying when trying to use the mouse wheel to scroll the browser and nothing happens because the browser no longer has focus. Granted, the continued crashing and audio issues that others are having are more critical.
