Thank you for the crash report link. Based on a bug report linked to your crash report, your computer appears to have the security software "Verdasys Digital Guardian" (or something that uses the same file name). According to the vendor, their software only works with the ESR version of Firefox, which generally is rolled out by IT departments. Does that make any sense for your computer?
