I came across this just today. I tried everything - emptying cache and history, disabling recent add-ons, upgrading her Firefox. Still nothing helped. So I backed up her Bookmarks, quit FF and moved Mozilla and Firefox folders from her Application Support Library (user>library>application support) to another location. Then I started FF and it was like starting fresh. I restored her Bookmarks, but all of her other settings were lost. But it worked! Seems some file in one of those folders is corrupted.
