User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release) Build ID: 20130511120803 Steps to reproduce: After waking up Firefox does not respond, but when i minimize the window and restore: browser has already reacted on my actions (mouse clicks), but is continuing not responding. Only restart Firefox resolves the problem. The problem appeared after updating to version 21.

Is your Issue reproducible when you disable the Hardware Acceleration under Options/Advanced/General and restart Firefox?

XtC4UaLL: I can verify that disabling Hardware Acceleration resolved the issue on my machine. OS: Windows 7 SP1 Browser: Firefox Version 21.0 User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0

Disabling of hardware acceleration doesn't resolve issue. It is still reproducible. But also, i noticed, it is reproducible when sleep mode lasts long. When sleep mode lasts short time it works fine!

I am having this exact same problem too. OS is Windows 7 Home Premium 64-bit. It happens upon recovery from sleep (not hibernation). Processor is AMD E-450 APU. As per the original reporter, the minimize and close buttons of the main window work fine, but opening up a new tab takes several minutes. I have the menu bar enabled, and when I click on a menu item, the drop-down menu appears very fast, as normal. However, when I move the mouse over various menu items, no menu item highlight appears on the item over which I am hovering. I am using the "classic" theme of the shell. I went to one of those "old apps" sites and downloaded and installed version 20. This fixed the problem. Disabling hardware acceleration does not fix the problem. I normally disable hardware acceleration anyway to work around the "ugly fonts" problem.

Same problem. Firefox 21. Windows 7 64 bit. Toshiba Satellite L675D, 4Gb. Any action takes several minutes after wake up. Fortunately, closing by Alt-F4 works fine.

Same Problem, it's exactly described by those above.

I have the same problem since I have changed my CPU from a dual-core to quad-core (Windows 7, 64 bit, 4GB RAM). Both Firefox 21 and 22 do suffer from this problem, but Firefox 20 does not seem to be affected.

I have exactly the same problem as well. Since the last Firefox Update, Firefox hangs up when the computer is woken from sleep. The only way to sort this is to restart Firefox. I am using Windows 7 Home Premium 64 bit.

Is there a way to modify this to include Firefox Version 22 or should a new bug be opened for that version as well for the same issue?

I also have this problem on my dosktop,I use Firefox 22 and Windows 7 x64 Ultimate.

Same problem here; Close/minimize work fine, but Firefox is largely unresponsive (some key presses are taken into account, but most aren't). Any new Firefox windows opened while the first one is frozen are also frozen (they open fine, but typing into the address bar doesn't work). Windows 7 x64, with AMD C-50 processor.

Many people say the issue have appeared since FF21 or FF22. So maybe there is a possible regression in one of these versions. For users who are able to reproduce the issue every time, could you use the tool mozregression (see http://harthur.github.io/mozregression/ for details) to find a regression range (provide the changeset). FF21 nightlies started in Jan 2013 (mozregression --good=2013-01-01). You need to define a workcase: set a power on-off session easily usable so you'll be able to wake up your machine fastly after mozregression downloaded and launched the nightly build.

Same problem. Running Win7 Pro x64 SP1 on a Dell Optiplex 755. No problems with FF20.

Can you please test with the latest beta? You can download it at: http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/latest-beta/win32/en-US/Firefox%20Setup%2023.0b4.exe

I might be jumping the gun, but the problem seems to have disappeared in Firefox 23 Beta 5. I'll report back in a few days after my laptop has suspended a few more times. This might encourage others to try it though.

In my box the Beta 5 works fine too.

Firefox 23 Beta 4 from Honza's above link (comment 16) has fixed the problem here.

Reporter and B_Cisco, could you confirm it's fixed with the latest beta, please. http://www.mozilla.org/en-US/firefox/all-beta.html

Sorry for the delay - very busy. Just installed the beta. Will let you know results ASAP.

Installed FF23 beta. So far, this appears to have solved the problem (came out of sleep three times). Many thanks.

Installed Firefox 23 Beta 4 and the wakeup problem seems to be solved.

Many users reported the issue is fixed with Firefox 23 beta, so I close it. Feel free to file a new bug (or reopen this one) if the issue is back.

Thanks everybody for testing this!

Marking verified-fixed based on many comments. This has probably been fixed by bug 836869.

Question: I noticed that there is now a beta 6 version available. Can anyone confirm that this fix is in the new beta? Thanks.

(In reply to B_Cisco from comment #27) > Question: I noticed that there is now a beta 6 version available. Can anyone > confirm that this fix is in the new beta? Thanks. The patch is in Firefox 23 since 2013-05-02 (when Firefox 23 was Nightly, now it's Beta).

Ok, after using the beta for a day or two, I can confirm that I no longer experience the issue. THANKS!

Hi, this bug seems to be the same like 890553 I can reproduced it on Win7 and FF22: -> Hibernate Windows 7 with FF22 still running -> change date in BIOS to the next day -> resume Windows 7 Than its present! FF23 works well...

My father encountered this problem and I got a remark from a friend of mind that had the same problem. I couldn't find a moztrap BFT testcase for this (but that might be my lacking search skills). If there isn't, we should make sure we get one,

What's the minimum amount of sleep time someone has to wait for this bug to occur? It seems, based on comment 4, simply switching in and out of sleep mode is not enough to trigger this.

If there isn't, we should make sure we get one, What you testing with? Which Firefox version?

Sorry, I can't tell, atm, I'm not at my parents place, currently. Iirc, it's on an amd64 bit machine, using Firefox 22.

Hi all, I commented on a duplicate bug https://bugzilla.mozilla.org/show_bug.cgi?id=859038, but figured I'd post here too. I'm still experiencing this behavior in Firefox 24 Beta on OSX 10.8.4 ML. Here's the graphics section from my about:support, let me know if you need anything else. Device ID 0x1189 GPU Accelerated Windows 2/2 OpenGL Vendor ID 0x10de WebGL Renderer NVIDIA Corporation -- NVIDIA GeForce GTX 670 OpenGL Engine windowLayerManagerRemote false AzureCanvasBackend quartz AzureContentBackend none AzureFallbackCanvasBackend none

Hi pmenon, could you please file a new bug for that and mention the bug number here?

Done: https://bugzilla.mozilla.org/show_bug.cgi?id=904958

Dropping the in-moztrap request since we lack the information to write a reliable, accurate testcase, and to ultimately decide if this is something which needs repeated testing in release. Please re-request if/when this information can be provided.

(In reply to Honza Bambas (:mayhemer) from comment #37) > This is confirmed fixed in Firefox 23. Can you re-confirm with your > parent's machine? Thanks. Yes, seems fixed, thanks. I haven't seen it back on my parent's machine on Firefox 23.0.1. They are using amd a6-3500 apu met with hd graphics 64-bit. I still think a general moztrap testcase might be useful. Something like, have Firefox open, then set the computer in sleep mode for 10 minutes or so and then after wake up, everything should work fine.

I had similar symptoms and found out that it was an upgrade issue of LastPath addon. Not FF issue. Versions: FF: 36.04 PC: Windows 7 LastPass: upgrade to 3.1.92 Symptoms: - Firefox can’t connect after PC sleep. - Trying to restart FF fails with a message indicating that a FF process is already running. - Attempt to kill FF process fails. Must restart PC. Problem cause: Upgrade of Last extension left a file – ‘Install LastPass FF RunOnce.lnk directing to ..\program files (x86)\common files\lpuninstall.exe Apparently this file was meant to be deleted automatically after the upgrade but it wasn’t. Solution: Delete (or disable) ‘Install LastPass FF RunOnce.lnk’ from startup directory. Restart PC.
