Have you just installed or upgraded to Windows 8 and Mozilla Firefox keeps crashing? That’s what happened to me. I had the latest version of Firefox, 14.0.1, the newest version of Flash, Shockwave, etc.

The fix?

I upgraded to Mozilla Firefox 15 Beta 5 (Still had issues).
**Update 08.21.12 – Upgraded to http://nightly.mozilla.org/ so far so good.

Firebug, Xmarks, Lastpass, etc. all still work fine. If you are having trouble with Firefox crashing, try grabbing the newest Beta. I have a feeling they have been testing a little now in Windows 8.
