User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0
Build ID: 20120601045813

Steps to reproduce:

Leave Firefox 13 running and close laptop.
Laptop is set to go to sleep (not hibernate) on close.
Wake up laptop / open cover after some while.

O/S is Win 7 Enterprise - Service Pack 1 - 64 bit

This is similar in behavior to old & closed (Mac) bugs:
426089
469459





Actual results:

Firefox 13 is unresponsive.  I can't switch tabs, refresh pages, type into address bar, or access any menu items.
To get it going, I have to kill firefox and restart it -- all other software is unaffected.


Expected results:

Previous versions of firefox just woke up and I was able to continue working as if it had never been put to sleep. Browsing, changing tabs, menus all worked
This is expected behavior

Developers would need a crash report to try and fix this so we need your help.

Please review and follow "Firefox crashes - Troubleshoot, prevent and get help fixing crashes"[1] and provide some Crash ID(s) of when you've reproduced the problem.

Whiteboard: [testday-20120615]
I am having the same exact problem.  I am using Windows XP.  I recently upgraded from Firefox 3 to Firefox 12 and now the latest 13.  I had no problems with version 3 but with 12 and 13 I have to restart Firefox every time I wake the computer up from either hibernation or sleep.  I also disabled add-ons and have the latest Adobe Flash Player.  This happens every time.  If I need to submit additional information please give me instructions and I will do so.
I also have this problem (Windows 7, FF 13.1). 

I had Firebug open when I put my computer to sleep, so I could see what happened when it returned from sleep. It looks to me like Firefox tries to do all the javascript work that it would have done if the computer never slept, all at once. If the computer slept for two hours, and javascript does an update every 5 seconds, it will try to do 1440 updates when returning! I had to actually kill the process because I didn't want to swamp my own server either -- Firebug reported over 8000 request rows that it couldn't display because the log was full by the time I decided to kill it. 

So in any case, there's a serious problem with Firefox' behaviour when returning from sleep. I understand some applications benefit from having its javascript executed as 'it would have', but seriously, the app developers should take sleeping computers into account, not Firefox. Please just freeze javascript when the computer goes to sleep! :)

I tried to get crash IDs but the problem is that the program hangs it doesn't crash so there is no report that I could find.

I do think you have the problem pegged.  If I wait long enough before trying to use Firefox after waking from sleep, it does come back to life.  I never had this problem with version 3 so I wonder what happened.

Firefox eventually did crash.  I was doing nothing with it at the time, I suppose it had just got tired of waiting to come back to life.  There is a crash report submitted: http://crash-stats.mozilla.com/report/index/bp-9a430f6a-6331-4401-8a46-f98f42120628.  If you need the details, I also saved them but I assume you will have access to them.
I would like to add to this that I am getting the same issues when I am resuming from hibernation on firefox 13.0 and recent 0.1 update

affected all 4 machines I own:
lenovo T420-windows 7 pro
lenovo T420-windows 7 ultimate
Desktop-windows 7 ultimate
Samsung R620 - windows 7 ultimate

all exhibits the same symptom when the firefox is loaded when the machines are hibernated, upon resuming, all other applications are responsive, except firefox.

older versions of firefox works okay. looks like I would have to revert versions.
I couldn't generate any bug reports as it didn't crash.
I am having this issue as well but only when resuming from hibernation. I open task manager and watch the firefox.exe process load several hundred megabytes into memory. Only when it finishes loading (circa one minute) does Firefox become responsive again.

Using
Windows 7 Professional
Waterfox 13.0

Safe mode and firefox reset did not cure the problem. Any fix is appreciated.
I just loaded version 14 and am still having the same problem.  For me it happens with sleep or hibernation and it takes a very long time to come alive.  I always have to close Firefox down and restart.  When I do that I get a message that says Firefox is already running and I have to try to restart it again.  This can happen a number of times before it finally starts up.

Using 
Windows XP
Gateway laptop M350WVN
Exactly the same issue here with version 13 as well as 14 on Windows 7 as well as Windows XP/SP2.

THIS ERROR IS ANNOYING, especially when you frequently hibernate (eg on a Laptop) and want to resume work - just to find all the tabs with articles you just have been reading frozen.

Currently my workaround is to use Firefox 11, which is not quite stable on flash videos (YouTube).
I can confirm this bug too, with Firefox 15.0 on Windows XP after hibernate. No response from Firefox when changing tabs. But after switching to another program that obscures the Firefox window, Firefox will redraw the window after switching back to Firefox.

I just updated to version 15 and the problem is still there but it is getting a bit better.  If you do something and then close the window and reopen it, you can see what you have done.  Still a problem that means I need to close the window entirely and restart Firefox but it is getting a bit closer.  I don't understand why the developers don't consider this a major issue that needs to be fixed immediately.
I'm running on Nightly and have seen this problem many times.
Came back home today after a couple of days where the computer was in sleep mode and found it to be basically unusable (while taking ~1.7GB of memory and ~25% CPU usage with only Facebook and Gmail open in the background) and I somehow managed to profile it using the Mozilla profiler :)

Oops, didn't notice there are no developers here :)
The stack seems to show GC as the culprit, does anyone know who to add to the CC list? or maybe how to triage the bug to javascript (it's greyed out for me)?
For those experiencing this problem (I'm not so can't debug it for you) here's what you should do:

1. Install Microsoft WinDbg: http://msdn.microsoft.com/en-us/windows/hardware/gg463009.aspx
2. Follow these instructions to run Firefox in WinDbg: https://developer.mozilla.org/en-US/docs/How_to_get_a_stacktrace_with_WinDbg
3. Let your computer go to sleep
4. After you wake your computer from sleep, see if it's hung.  If it is, follow the instructions for getting a stacktrace "After the crash or hang"
5. Post your log here
(In reply to IU from comment #15)
> 5. Post your log here

I mean attach your log.  Please do not post it as a comment. :-)
IU- I'll try and get a stacktrace with windbg (had problems with it and just realized I was running the 64bit version from the SDK) but can't the profile I gave help in any way?
I know nothing of the Mozilla code base and even I know that 82% of the time spent in js:GCSlice is no good... does it not have enough info?

In any case, I'll try and get windbg working :)
I can't get windbg to play nicely with firefox...

Whatever I do it hangs right on startup (even after disabling all addons), the only way it doesn't is when I start it in safe mode (via passing -safe-mode to the program's arguments).
Could this be a new issue with the nightly?

windbg doesn't affect firefox. so if it doesn't hang on startup without windbg then something else is happening. Like an assert on startup.  You can probably ignore most or all asserts and give a "g" in windbg, to just go past them.

I can't press 'g' in windbg because firefox doesn't crash, windbg says 'debugee is running' but the main firefox window is just hung while taking no cpu usage...
If you'd like I can break on it while it's hung and follow the instructions above to get a stack trace...

The document I linked states: "If Firefox hangs and there is no command prompt available in the debugger, open the Debug menu and choose Break."

So, you first press 'g' to make sure that it's not just a debugger break waiting for your response.  If you press 'g' and the Firefox is still hung, per the line I quoted above, you break and follow the instructions under the heading "After the crash or hang".

From the stack trace, I notice you have some extensions (for instance, ghostery).  Have you tried with extensions disabled?

Yes, like I wrote above- "(even after disabling all addons)"...
Having said that, I just tried playing with the addons again and it's now working- weird... :)

So forget about that log and I'll get you a stack trace the next time the problem happens...
Attachment #666284 - Attachment is obsolete: true
I can't get firefox to run with windbg in a consistent way (one time it works, the other time it doesn't), and this is with no addons!

IU- like I said, I'll try and get a stack trace soon (once firefox plays well with windbg) but you still haven't answered my question- is the profile I posted (not the attached file but the Mozilla profile URL) not helpful?
(In reply to Barak Gross from comment #25)

I'm not actually a dev -- just a lurker. :-)

What do you mean by "in a consistent way?"  What is it not doing?  Note that, if you WinDbg breaks debug, this is normal and happens anytime some external module needs to be loaded.  Just press F5 (which issues the 'g' command) to continue debugging.

By "in a consistent way" I mean sometimes firefox freezes just like I described in comment 20 (where firefox is 'running' and is just hung and not responding and windbg did not break for debug) and sometimes it starts up perfectly (the previous attachment is after I manually broke like the URL describes so it should point to the same intermittent problem I'm seeing).
Like I said, I'll try and get a stack trace with windbg but what's the point? if no one's looking at what I already posted who would look at the stack trace when I do get one?
I just upgraded to version 16 and the problem has gone away.  Thanks.

Sorry, I spoke too soon.  It still hangs from hibernation.
Based on comment 10, it appears this issue exists post Firefox 11.

If any of you having this problem is ambitious, a good bet would be to bisect nightly builds between Firefox 11 and Firefox 12 until you find the build that first introduced the bug.  The build dates would thus be between March 13, 2012 and April 24, 2012; thus, not a huge number of build to test (especially if bisecting)

You can find those mozilla-aurora builds at these two URLs:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2012/03/
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2012/04/

That would help narrow things down dramatically.
On second thought, that range I provided will not work as the bug may have been introduced much earlier, so you would have to use a mozilla-central nightly build.

you will actually need to bisect nightly (mozilla-central) builds from December 24, 2011 to April 24, 2012.
Hi everyone,

great someone is actually looking into this.
I have experienced the same behaviour for
about a year now on my Windows XP x64 system.

Running the nightlies, I managed to bracket
it in to the following dates. Unfortunately,
Firefox does not run at all on my system for
a certain interval of snapshots.

So the bug is likely introduced somewhere
between December 9 and December 15, 2011.

Any of the developers can check the ChangeLogs for
this period to see what the major alterations to
the code base were at this time?

How could I do this myself?!

Best wishes,
Oliver

'TimeStamp_windows.cpp' might be a candidate since it deals with timer
issues after system wake-up. Wild guess however, as I'm not a developer.

Could you please try the "mozilla-inbound" builds from December 7 to December 14, to see if that makes any difference.  If it still fails to run, try switching from the installer build to the zip build, or vise versa; and uninstall/delete the previous firefox program files first.
(In reply to IU from comment #34)

I now ran the "mozilla-inbound" builds,
i.e. firefox-11.0a1.en-US.win64-x86_64.zip
and got the following regression:

 2011-12-07	working normally
 2011-12-08	working normally
 2011-12-09	unresponsive after resume from sleep
Thanks, Oliver.  Could you please try one more test.  Please test with a recent Aurora nightly build to see is the problem still exists.

So far I suspect that you may be right and that it was caused by bug 676349.  However, don't add blocking until you've confirmed that the bug still exist in a current nightly.  Thanks.
(In reply to IU from comment #36)

Just tested today's (2012-10-30) nightlies of

firefox-18.0a2.en-US.win32.installer.exe
firefox-19.0a1.en-US.win32.installer.exe

and they both still show the bug.

I can confirm this behaviour. If after resume you wait long enough before using it, it works normally.

How long is long enough?
By the way, could you also provide the URL you were on when you were able to reproduce this.

No particular URL opened. Just the Firefox startpage.

Hard to say. The time it takes to prepare a coffee.
In any case long enough to be annoying.

Since we seem to have pinned the date it first appeared, is there a way to patch the suspected module with an earlier version and try if it changes anything?

I've never made such builds before.  Nonetheless, I'm CC'ing Honza, who worked on the responsible patch, and adding blocking so someone more skilled than I can take a deeper look.

This may not be possible with mozilla-inbound for 2011-12-09 because it is missing the win32 build.

@Oliver:
The builds you indicated, in comment 32, would not execute, were those 64-bit builds?  If so could you please try 32-bit mozilla-central builds.

@Wayne:
It still would be a good idea for someone to create a build with the bug 676349 patch removed.
Here are win32 and win64 builds with the original timestamp implementation (bug 676349 and followups effectively removed).  Please try them.

For about a year now, my computer goes to sleep every night and also every 2 hours of inactivity and yet I encountered the bug only the one time, so it's doubtful I'll be able to get the stack trace.

isn't most everyone able to easily reproduce this?   In which case, I'd think UI's issue is different from what others are seeing.

apparently I didn't explain enough - which is that windbg need not be running when you hang for you to get the stacktrace.  You can start with just a hung Firefox
1. firefox hang
2. start windbg
3. attach windbg to firefox process
4. obtain stacktrace
Attached windbg to firefox after resume from hibernate.
I assume firefox still hang when I did this, cannot say for sure, though.
First time I did a stack trace, so feedback welcome.

Maybe the timer for the refresh driver doesn't get restarted properly after resume? That could make it seem like Firefox had hung.
Actually what I experience is that, after resume from standby or hibernation, the UI would not redraw when firefox remains focused. Once firefox losts its focus, the UI gets redrawed in the background. I think it is more like the description in bug 788171(Comment 16). Maybe a duplicate report?
Anyway, since the UI did gets redraw(although at wrong time), it's possible that the problem is not due to deadlock.

FYI, I did install the build you offered, http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/honzab.moz@firemni.cz-010c22886173/ and the problem goes away.

Yeah, what you describe sounds like the refresh driver timer not getting restarted.

And bug 676349, comment 68 seems to indicate how this is failing.

The refresh driver is responsible for driving painting, it lives at http://mxr.mozilla.org/mozilla-central/source/layout/base/nsRefreshDriver.h and it uses time stamps. If time stamps somehow got screwed up it might screw up the refresh driver.

I wanted to point out bug 676349, comment 68 here as at the time it looked like it was the best insight into this problem that we had. I don't have any better info.
Flags: needinfo?(tnikkel)
I'm also seeing this (on WinXP with Asus EeePC 1000H). And when it happens, I'm seeing it with FF and Thunderbird at the same time. I guess both share the same timer implementation? This would explain why they either both fail after hibernation, or they both don't fail.
I believe bug 746345 and bug 788171 also refer to the same issue.

Thanks Timothy, I also got some interesting feedback from Rong in bug 676349.

I'll look at this soon.
Finally getting to this.  I think I know what is the cause, thanks again for leading me to the refresh driver.

After the wake-up TimeStamp::Now() returns GetTickCount() + sSkew where sSkew is way too old.  We recalibrate because of waking up and TimeStamp::Now() now uses value of QueryPerformanceCounter().  Since sSkew is very old, difference between GetTickCount() + sSkew-before-recalibrate and QueryPerformanceCounter() is deep.  I presume that we make a big jump back.  But since there is a sentinel code that disallows TimeStamp::Now() going back, we for a long time return the same value - the last value of GetTickCount() + sSkew just before recalibration.  This makes the refresh driver think the time has stopped.

Solution here really is to disallow force of recalibration when flaw in QPC has been detected a longer time ago, say 10 seconds, but not when detected right after waking up.

I'll crate a patch for it.

I'm not sure about the x64 version, but the win32 version fixes the timer problem.

Meanwhile, I've created binary patched dll files for the released version of firefox using ollydbg. It can be a temporary solution if you want to stick to the release branch:

The win32 build doesn't work for me, either.
I'm running the above "firefox-20.0a1.en-US.win32.zip" on WinXP (Asus EeePC 1000H) for 1,5 days now, haven't seen the issue again. Right now, as a test, I did 10 hibernation cycles: every single cycle triggered the issue with Thunderbird 17.0 (which suffers from the same issue), but none affected FF-20.0a1 running on the same machine. Before the patch, when the issue occurred, FF and TB both used to be affected at the same time. So for me the issue indeed seems to be fixed. Thank you! :-)
Oliver, can you please run the test build of firefox with following environment variables set?

NSPR_LOG_MODULES=TimeStampWindows:5

Just did this with the x64 version. Started Firefox, opened a few tabs and then put the system into hibernate. When back from resume, I changed tabs and clicked on a link. Firefox would refresh after "Alt-Tab" to a different window (text editor) and back.

Hope this helps. There is one ":(" in the output, so fingers crossed.

- the same as v1 except the wake up retry acceptance interval shortened to 2 seconds only since I don't believe we will be getting on-wakeup notification later after waking up then in such short time
- introduced "wake up adjust" to compensate difference between GTC + skew determined before sleep and QPC after waking up (see bug 822490 for explanation)

I also forgot to mention that I did not start having this problem until upgrading Firefox. I was using a very old version before and I did not have this problem
