Comment 5 for bug 298090

Forget it! I fixed it myself.

Next time one of you poor souls have a strange problem in Firefox just uninstall it completely then delete every .mozilla and .firefox directory you can find (primarily in your home folder). You can then install it again and all will be fine. I suspect that it had something to do with the cache files and folders because when I deleted a bunch of those my problem went away, but my bookmarks and customized plugins as well. I didn't like that so I decided to simply wipe it clean and start from scratch. That worked.
