I reconnected Java 7 plugins (out of date) I have the same crash: bp-0e218b38-a17f-4e14-aef4-e30132160318 But I have no crash in Safe mode.

Create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

AshShell.dll = Windows

ashtask.dll = avast! Antivirus = AVAST Software

Note: The last two crash reports are not showing high memory usage

AVAST has been known to cause Firefox problems. As a test, disable it. Also, check for updates.

Thanks all for help. I found the source of my problem. It is one of memory module DDR2 2Gb that i bought on ebay. I have tested all memory but no found any errors. But Firefox crashes when I used the particular memory module. I do not understand that fact that only Firefox crashes, all other program works normal. I had to pull a strange memory. It now remains 6Gb. May be I will use it from time to time, when I need in 8 Gb. :) Now try to restore Abobe flash plugin in Win XP 32bit. As I found it was not a trivial task. A simple installation does not help for some reason.
