Scan your computer in safe mode for bots, malware, trojan's and viruses. Remove any Found and reboot. If Problem still exists, go to control panel, add/remove programs remove firefox. and then download and reinstall firefox. Remember to always close as many running programs like messangers and widgetts when installing any program. This should fix your problem. only other option is to do a system restore to when you were not having any problems, this works 90% of time.

I have no idea how to do either of those things. When you say to scan my computer in safe mode for bots, do you mean my whole computer or just Firefox? Either way, I have no idea how to do that. Also, I have removed Firefox, did a restart and then re-downloaded the app in Safari and I still get the same crash. What about a system restore? Can you explain how I accomplish that? Thanks for your help Vi_Nemo.

Hello again Vi_Nemo,

Just wanted to let you know that I did some more research and found my answer. I created a new profile and it fixed the problem. Unfortunately I've lost all my of my valuable info such as bookmarks, passwords and such but at least I've got it working again. It's the only browser I enjoy using. I did find on the Mozilla site how I can get that information back but I'm afraid if I do I'll just crash my new profile. : 0 (. Oh well. Thanks again!
