365835 - FireFox randomly freezes my entire computer while browsing....HELP!

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[matt]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7

I recently upgraded from 1.5.0.7 to 1.5.0.9 without installing any new applications.  I then started to experience random freezes when I have firefox running on my computer (Windoze XP SP1).  I must then reboot my computer and then I will start firefox up again and it will again freeze (sometimes it's 4 minutes later, sometimes 1 hour later). 

 I'm not sure what the problem is because I haven't installed anything lately, therefore I tried reverting back to 1.5.0.7 and now even it freezes on me!!  (Perhaps that is because I did not actually "uninstall" 1.5.0.9, I just installed over it??)

Please advise!!  Is this a known bug within 1.5.0.9??  Thanks

See http://kb.mozillazine.org/Firefox_hangs for diagnostics.
Could first try safe-mode to exclude extension/theme problems:

Firefox can't freeze the whole OS.
The reason why Firefox can't do this is that Firefox is a userspace application and it doesn't install drivers that are running in the kernel mode.
Your problem looks like a problem with hardware or with a driver like the graphic card driver, network card driver, firewall or antivirus driver).

marking invalid (bugzilla is not for support questions).
