Why is Firefox crashing? No error or reason is given. Uninstalling and reinstalling Firefox/Shockwave/Flash does not help. I have no addons.

Question

Firefox randomly closes every time I go to do something, like use Google or Yahoo (it will NOT close if I let it linger). It would also close immediately when I tried to use a hyperlink through Word. When I go to open it back up, it will say that it cannot restore the previous session and there are no crash ID's of any kind.
I have no addons or extensions, and thus they cannot be causing this. I've uninstalled/re-installed Firefox, Shockwave, Flash, and Java. I've wiped my cookies and history. Nothing works. My other two browsers, Internet Explorer and Google Chrome, are working fine.
What could be causing this?

Answer 1

You can try to do a malware check with some malware scanning programs on the Windows computer.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of their databases before doing a scan.
