Hardware acceleration was already disabled when the issue was occurring.

Jim, cc'ed you as this seems similar to bug 627084.

Adding the SUMO contributor forum thread where this is being discussed to the URL field.

### Comment 5

In the past this was caused by a lost or out of sync native event mechanism we have down in app shell. When we want to process gecko events on the main thread we post a native windows message to a window [1] which triggers processing gecko events [2]. We also introduced a safety mechanism that primes native event callbacks if we haven't processed one in a long time in bug 627084.

Reports indicate this regressed in Fx25: 2013-06-24 - 2013-08-05.

Finding a way to reproduce so we can track down a regression range in nightly installs [3] would be great.

But maybe some users affected by this issue can install the tool mozregression to find a possible regression range: http://harthur.github.com/mozregression/
FF25 nightlies started in June 2013 (mozregression --good=2013-06-01) they just need to past the console output.

Eddy, can you ask a user to test that, please?
(Reporter)

### Comment 9

4 years ago
Ok yes I'll ask them. I've not used the mozregression tool before myself so I'm having a bit of trouble describing exactly what the user needs to do. Is this a good description?

"If possible it would be a huge help to our team if you could run the mozregression tool. See instructions here:

http://harthur.github.io/mozregression/

This tool will let you test against various versions of the nightly channel of Firefox to establish when the bug was introduced.

The version which has introduced the issue (v25) started in the nightly channel in June so if you start with the command:

'''mozregression --good=2013-06-01'''

That should establish a case where the bug does not appear. You then test against each version until the bug appears. Once you find a case where the bug appears please paste the console output into the reply box below. That should let us identify the exact version of nightly (and therefore the changes made) that introduced the bug."

### Comment 10

Since we already have a discussion forum thread on this topic, it would be really great if the developers working on this bug wanted to join there. It would save the bug some clutter and SUMO contributors are really craving more interaction with developers!

Also, several people claimed they had the issue before updating to 25. It's possible something else updated near the same time and people just noticed the Firefox update and assumed that was the cause since Firefox is the affected program.

Not really, but this sounds pretty bad, so I'll try to make some time this week.

It is pretty important to know what versions of Windows this is affecting. I asked on the SUMO threads, if anyone has any additional data, that would be great.

We could backout the patch from bug 896896 from (say) 25 and 26 whilst I work on a fix - given that I can't repro this, that might not be quick. The bug we fixed with 896896 only manifests with OMTC, which is close to zero users on Windows for now, so I don't think we'd be introducing more bugs.

You can safely ignore the metro changes on all repos since we have updated that code and removed the wait (m-c/m-a), or it's not in the repo at all yet (m-b/m-r).

I am having this issue since the auto-upgrade to r25.  I use Firefox pretty exclusively so I know this started with the r25 upgrade.  Browser just stops loading unless I keep moving the mouse.  Watching a video even will continue to play the sound but the picture will stop unless I move the mouse.

I am on Windows 7 SP1 64-bit.  It is a Gateway SX2801 machine.

Thanks for reporting this. Could you file a separate bug please? It is probably coincidence that it happens with 25.0.1 and not connected with this backout, after all we just reverted to earlier code. Not sure what would cause the darkened screen, sounds like something the OS would do, but I've never had Windows do that to me unless it is opening a security dialog box.

ok thanks for clarifying, i've probably just assumed that this happened after an update from 25.0 to 25.0.1, but actually it doesn't say that directly in any of the threads. so i'll wait if we can get any further in troubleshooting the issue in the sumo forums before i file a new bug...

Hmm, I wonder if I spoke to soon - if you don't respond to Windows messages for some time, Windows replaces you with a ghost window, which might have this effect. However, that we've been with the previous WaitMessage implementation for years without problems and that refreshing the webpage still works, makes me think they are unconnected still.

I am trying to work out a long term fix for this problem and need some help from users who can reproduce it (I cannot).

I am not currently seeing the problem since installing 25.0.1.  However, if I view a video (such as something from YouTube) and select full screen, it still shows the behavior.  I don't see this with videos in full screen from Chrome.

Anyway, I am willing to do testing since I did see the problem with the last release of Firefox I was on if that is good enough.

Build 1 (without the fix, with logging): http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/ncameron@mozilla.com-ed7bd96a1254/try-win32/firefox-28.0a1.en-US.win32.installer.exe

Build 2 (with a different potential fix and some logging): http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/ncameron@mozilla.com-fd2184b61c29/try-win32/firefox-28.0a1.en-US.win32.installer.exe

I would be grateful if Andy and others could install and run these two builds, they are both nightly versions of Firefox from last week some time with some minor changes.

I would like you to run build 1 until you observe the locked up screen behaviour described in this bug, then leave it for 10 seconds or so (so it is obvious in the logs) and then exit Firefox. For build 2, I would like you to use it as normal to try and cause the problem. Let me know if it still occurs or if it is fixed in this case.

In both cases there should be one or two log files created in Firefox's working directory. They will be called nrc_crloop.log and nrc_msgloop.log. Don't worry if the first is missing, but the second one should always exist. Please email me these logs (ncameron@mozilla.com) and your observations (or email a link to them in Dropbox or something if you prefer). If you could also include the information from about:support, that would be helpful, but is not essential. The log files are plain text, you can inspect them before sending (but please don't modify them). They contain no personal or identifying information and no information about the webpages you viewed.

If you have any problems doing any of that let me know here or by email and I'll do my best to sort it out. Thanks!

I suspect that is a separate problem, but if you could try this with the experimental builds too, that would be great.

Yes, that is fine. There is a temporary fix in 25.0.1 so it should be fixed for everyone, but I am trying to find a different, more long term fix. It would be great if you could help out :-)

Pinging the thread again. It would be really awesome if someone could test the build above - it is essential for getting a long term solution to this bug in Firefox. If I can do anything to help you test, just let me know. Thanks!

### Comment 57

I don't want to add noise to this bug, but I wanted to mention that this behavior sounds potentially similar to the effect of the (ancient and poorly understood) 'favor performance' mode that smaug is removing in bug 930793. If that were the cause, it sounds like it's getting enabled permanently somehow and only getting turned off briefly when user input happens - but that's a complete guess. Might be a complete red herring, but since this sounds like pretty arcane event loop stuff I wanted to make sure it's on people's radars.

### Comment 60

4 years ago
My dad is visiting, so I have direct access for a while to the windows laptop that exhibits Bug 912521 consistently. But perhaps more interestingly to followers of the report here: On the first run of today's Nightly I experienced the problems reported here on it, immediately on startup, where any form of progress is halted until I wiggle the mouse. Things like page loads after clicking links (or even information-expanding buttons on the same page) cause everything to pause until I move the mouse. This happened consistently for the whole session, i.e. the browser was "ill" for the whole session. But I have restarted Nightly many times since and not been able to see the problem again, except once I thought it started happening where a link exhibited the problem after I had reproduced 912521 with a frozen video.

Since I've not been able to reproduce anything consistently, I'm not sure how much help I can be, but I wanted to mention it. What was interesting to me was that on runs where it got ill, lots of stuff freezes when the mouse isn't moving, from video (though not audio), to page loads (though a nudge seems to cause page loads to complete in full), to progress bars, like the "Nightly update" spinner. The user experience is quite horrible when it happens. Moving the mouse gives temporary relief only.

Thanks for trying the builds, I suspect this might be because you do not have permission to create the log file and then my (rather hackey) code just crashes because it assumes the log file will be OK. Could you try installing Firefox somewhere where Windows will let you create files (which means not 'program files', annoyingly). Alternatively, you could try running with a specified working directory which you can write to, or running with administrator privileges.

It is expected that nightly and aurora are still broken. We only landed the temporary fix here to release and beta versions, hoping for a long term fix for aurora/nightly before it becomes an issue for users. Thanks for all the info!

Oddly, I'm able to reproduce it quite consistently now, just hitting the different topic-tabs on cnn.com. I waited more than 10 seconds to make sure it was really frozen and not just loading slowly, then I moved the mouse, observed the page building and quit Firefox after a few seconds.

Not much in the logs, so I'm pasting it here:

Much better, or the timing changed.

I'm no longer able to reproduce it using the same steps as before (switching topic-tabs on cnn.com). However, after 10-20 runs, I had it happen on browser startup twice. In those cases, visuals freeze during the moonring spinner and the "Connecting..." message in the tab header, during the loading of my google.com homepage. As usual, moving the mouse wakes it up.

Do you have the logs for this run please? Unfortunately I think the improvement is only due to a timing change - all I did was add logging to this build. I fear this is a very timing dependent bug :-(

My dad says he thinks he's not seeing the refresh-pause-until-he-moves-the-mouse problem anymore using your FF download (though note he still sees Bug 912521 which is why he stopped using Firefox).

However, he did see a new problem, which I observed as well over Skype with him, which may be related or it may not be:

When he scrolls down a page on cnn.com using the dedicated scrolling area of his trackpad, when he lets go and the odd vertical rectangle symbol disappears, instead of getting his mouse cursor back, his mouse turns into the blue MS spinner. This stays spinning until he moves the mouse, at which point he gets his regular pointer back. Nothing else appears frozen or snaps back.

That means we also need to backout OMTC from all these branches, and any dependencies. Without bug 896896 our event loops bugs actually cause much more frequent freezes when trying to use OMTC :).

Vladan has asked me to look into this. I'm attempting a rewrite of WinUtils::WaitForMessage that should play more nicely. I'm testing out locally to ensure that it doesn't break anything obvious but we'll probably need help from those affected users to know for sure whether this fixes the problem conclusively.

Yes, sorry for not being clear. For the 32 chemspill we're all good with the backout. We'll need to try and fix this for Beta/Aurora.

I'm not sure if I have seen the same while I was running yesterdays (Sep 18th) nightly with e10s enabled, but the whole content area was not redrawn until I have moved the whole window with the mouse. So in my case it was not enough to simply move the mouse. Restarting Nightly made this problem go away. A look into the console reveals the following lines to be listed:

Bug 937306 and bug 1072752, that is. Though I guess we're sorely lacking in any confirmation from affected users :(

### Comment 129

Yes, we sorely need confirmation that this isn't happening on current 33 Beta versions. If we cannot get confirmation, we run danger of releasing once again with this bug in place.

Also note that we can't just solve this with a backout any more as OMTC requires the work from bug 896896 and 33 shows broken behavior in multiple cases without OMTC.

So, please, if you saw this bug on Windows in previous releases/versions, *please* help us and test current Firefox Beta - and tell us if it's fixed there!

That seems like a rendering problem rather than a WaitMessage problem and is probably a different bug. It is unlike the symptom here which is that rendering pauses entirely until a mouse move input event unfreezes updating, at which point the whole screen appears normal without rendering errors.

We still get a number of people reporting this issue on 33 release - however in most cases it turns out that malware is involved and the issue can be addressed by using some scan tools like adwcleaner or malwarebytes to remove unwanted software.
one user singled out "VideoDownloadConverter" in particular as causing the issue: http://www.camp-firefox.de/forum/viewtopic.php?p=941172#p941172

aklotz, is there any information John could give you to help track this down? e.g. NSPR logs?

John, do you use Flash? Could you try completely disabling Flash in the addons manager and see if this still reproduces?

I deactivated Shockwave Flash, relaunched browser and it still hangs until mouse is moved.

Any chance you could update your NVidia drivers to v344.60 to eliminate it being GFX related?

I upgraded the driver to v344.60, also updated FF to the new 33.03. Did a restart on the machine and the issue still exists.

John, would you mind downloading and installing procdump from
http://technet.microsoft.com/en-us/sysinternals/dd996900

Have a command prompt open when you run firefox. When you encounter the problem, run:
procdump -accepteula firefox firefox.dmp

and attach the resulting firefox.dmp file to this bug?

The output by default does not include process memory, so I don't expect privacy issues. If you would rather provide the output directly to me, do not hesitate to send me an email.

Error creating dump file:

I tried turning off firewall and it didn't help. I'm running as admin so I don't know where this is coming from.

The other potential problem is when I load a page in FF and it instantly freezes, then when I alt-tab, or click to the cmd window the browser continues to load without hesitation since it's not the active window.  The freezing only happens when FF it the active window.

That's interesting and useful feedback, thank you!

OK, alternative plan:

Which directory are you running procdump from? That could by why you're seeing access denied. I'd suggest running it from your %USERPROFILE% directory ( C:\users\<username> ).

Let's try this:

1) Start firefox, prepare to repdroduce the issue (but don't initiate the repro yet);
2) Run:
procdump -s 5 -n 6
This will set procdump to obtain 6 dumps, 5 seconds between each dump, giving you time to switch back to Firefox and reproduce the issue
3) Switch back to firefox and reproduce the issue
4) Wait for procdump to finish (~30 seconds)
5) procdump should have generated 6 .dmp files as output.

I don't know that it matters but is this a PS/2, USB, or PS/2-to-USB type mouse? Is it using the generic Windows driver or a vendor-specific driver? What brand and model of mouse is it?

Was Flash enabled or disabled when you obtained these dumps? One of the dumps is on a code path involving plugins, so either Flash was running or something else (maybe Silverlight?) was.

Flash was disabled. I ran a YouTube video during the test because those freeze as well (sometimes the audio still plays [buffer?] but the video stops). If I click off the browser page and make any other window active the freezing goes away and the content loads.

This behavior in FF seemingly began immediately following an update to Adobe Flash Player in Win7-32bit.  It is occurring on a friend's computer, so I don't have it in front of me at the moment, but got a call tonight reporting this no-loading unless mouse is constantly moved.

Hello
I've the same bug, but can't remind since when.
The page doesn't load if I don't move the mouse.
The problem occurs only when Firefox is the active app.

Mouse G500s logitech
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0

manarbre, can you try to run a scan of your system with the free version of malwarebytes from https://www.malwarebytes.org/mwb-download/ (automatic download)?
i case this tool finds malware & removing it can address the loading issue issue, please attach the scan log from malwarebytes to this bug report...

I've found the solution for me.
It seems to be ShrinkPic, a little software which shrinks JPG on the fly, for mail or web...
Desactivating it operates firefox and pages are loading normaly, without moving the mouse !

I can indeed reproduce this on a fresh install of Windows 7 x64 (fully updated), with Firefox Nightly and Shrink Pic [1] on my VM. Nightly seems to hang while pictures are being loaded until I move the mouse.

It looks like that software has not been maintained for 5 years. I'm not sure there's anything we can do in Firefox code about that.

Sure, it's easier to not start this software at windows's startup.

I'm just confirming it as a way to reproduce the issue, since as far as I know we've had no way to do that until now. Worst case we can probably block whatever hook the program is using that's messing us up, but it would be nice to know where things are going wrong.

Indeed, whatever they do in this app others might be doing.

Yeah, that's fair. What do you need from QA to move this forward?

FWIW, I'd prefer if we forked further work of this issue to a new bug report. The original case for this has been fixed a few releases back. I'd find this easier to follow if we had a separate bug report linked to this one.

A fresh bug sounds like a good idea. Not sure QA can help much here, we need to get an engineer poking at this app when we have free cycles.
