Hi tbeach, You should take a look at the Knowledge Base article [[Updating Firefox]]. There is a lot of good information in there and some troubleshooting steps as well. If that doesn't work, you might want to try installing a fresh copy of Firefox: http://www.mozilla.org/firefox/new/ I would suggest that you first back up your personal information and bookmarks, just in case. You can find details in the article [[Backing up your information]]. Hopefully this helps!
