This is a RtlpWaitForCriticalSection crash and I read the article on dealing with it to discover the probable cause. However, I don't know what the file is and how it could interfere with my web browsing. Any help? I also noticed that I'm getting frequent crashes with other browsers as well (IE and Chrome, Safari seems to work fine). My most recent crash report is linked below:

I had this same problem and it was getting worse and worse until I couldn't open most sites.

I'm not sure exactly what fixed it, but I cleared ALL of Firefox's Cookies and Cache and also performed Disk Cleanup on all of my drives (Temporary Files, setup logs, etc.)

This did the trick and I'm back up and running without problems.
