I am running Windows XP SP3 and Firefox v3.6.2 and have an issue with Firefox causing the Blue Screen of Death. If I run in Windows safe mode, it does not occur, but running normally, it seems my firefox profile is going bad and results in certain web pages causing the BSOD. For example, presently, if I visit ebay.com, it gets BSOD. Before it was happening on google.com, but IT removed my Firefox profile and that seemed to fix the Google failure. However, now it has started occurring on ebay. I turned off all extensions and it still occurs. I'd like to fix my system so this does not occur. The IT folks don't seem to be able to solve this, so I am trying to fix it on my own. The BSOD is about something like (from memory) IRQL_NOT_LESS_THAN_OR_EQUAL.

Why would safe mode avoid the issue and what does that tell us about the probable cause?

I don't want to have to keep deleting my profile, so I'd like to find out the cause of the corruption.
