884584 - Firefox hanging on computer's return from sleep

Status: RESOLVED INCOMPLETE

(Core :: XPCOM, defect)

Description

[Ed]

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:

1. I have a lot of websites open (see attached dumpfile)
2. Put my computer to sleep (Windows 7 64b latest updates)
3. Wake the computer


Actual results:

1. Firefox is wedged.  It seems like after a minute or two it will respond to a mouse click.  I see a little bit of CPU usage, a little bit of page-faulting in the process - so something is whirling.  The 'close' button at the top-right of the app is still active, but basically nothing else is active in the app - can't switch tabs, scroll, when I move the cursor over a tab it doesn't change to the hand, etc.
2. If I stop the process from Windows Task Manager ('End Process') and restart Firefox, restore all tabs, get the same wedging behaviour.


Expected results:

1. Firefox no wedge

I read some reports about this issue and recent Firefox versions.
For the record, a previous bug about the same issue: bug 765215.

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0

On the above given build i tried the steps and indeed Firefox is being put out of business for a while longer that Chrome or IE9 - considerably longer. But if I give it some time, it works again.

Maybe a little regression from  bug 765215?

Another repro:
1. 5 windows open, 10-20 tabs open in 2-3 of them, a handful in the others.
2. Firefox reports there is a new update (22.0).
3. Install update
4. Restart firefox
5. Windows and tabs are re-opened automatically
6. (close 2 of the windows)
7. put computer to sleep
8. Wake computer

actual result:
- firefox is wedged.  Doesn't show "unresponsive" message in title and UI paints OK, but nothing is responsive - scroll, menu, tabs, etc.

expected result:
- everything works correctly

Note that this is NOT just "Firefox is out of a commission for a little while".  Firefox frequently does that as well, but this bug is about a long-term wedge - it never (in my experience) starts responding normally again.

Ed, a similar bug to yours has been fixed in Firefox 23 beta (see bug 873110).

Could you install FF23 and test, please.
