I Can't Believe How Much Firefox SUCKS Anymore
Crash & burn, crash & burn. All Firefox seems to do anymore. That is when it's not hanging and/or slow. Firefox crashes so much that I just leave Windows Task Manager running so that when Firefox crashes/hangs, I can just kill the firefox.exe process, restart it & then use restore to get back what I was doing . . . for a little while. Then rinse, repeat, rinse, repeat, rinse, repeat. Firefox USED to be the best browser, bar none. Now it's just the same 'ol crap that everyone else has. May as well go back to IE. At least I expected it from Microsoft.

firefox has become more anti-malware strategic. but for the most part, its pretty good.
what i am thinking is that firefox may not be problematic. but instead your system is unstable in some way.
