305330 - 100% cpu usage after exit from hibernate mode

Status: RESOLVED DUPLICATE of bug 265172

(Firefox :: General, defect)

Description

[Alexander Pevzner]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

If system with running Firefox browser put to hibernate mode (sleep to disk) and
then awaken, often the browser becomes to use 100% of CPU. In this state it
remains responsive, but system significantly slowes down. Once in this state,
100% CPU usage doesn't disappears automatically. Only the browser restart helps.

This problem appears under WinXP. It appears not only with Firefox, but with the
Mozilla browser as well. The problem seems to be outstanding, it appears with
all releases during at least several last months.

Reproducible: Sometimes

Steps to Reproduce:
1. Start firefox and open some web page. Wait till page is fully loaded.
Hibernate mode must be enabled in the Control Pannel
2. Put system to sleep mode (i.e., close labtop lid)
3. Awake the system and wait unitil it finaly up and running
4. Press Ctrl-Alt-Del and look to CPU usage. Often, but not always, Firefox eats
100% of CPU time.

It seems that this problem is better reproduceable on a complex web pages, with
animated pictures and so on (but normally, i.e. before hibernate, these pages
don't consume 100% of CPU).

Actual Results:  
Firefox uses 100% CPU time

Expected Results:  
Firefox should not do it :-)
