Cammy, it sounds like somehow your Firefox profile has been damaged. Unfortunately, it will mean setting it all up again, including reinstalling any plugins you were using, but this is what you need to do. First uninstall Firefox, then navigate to C:\Documents and Settings\[yourname]\Application Data\Mozilla(if present)\Firefox\Profiles\[xnxnxnxnx]. When there, if you have stored Bookmarks since using Firefox, open the folder and take a back up of the 'Bookmarks' file, for future use, then move the entire Firefox folder to another location. If you also have passwords saved, you can back up the 'key3' database file, and the 'signons' text file. When you then re-install Firefox, it will create a new profile. You can then go back into the new profile and overwrite the Bookmarks file, if you want to preserve your Firefox Bookmarks, and the same with the passwords (key3.db, and signons.txt), if you also have Passwords stored. You may have to create a saved password first, in order for there to be a 'signons.txt' file to overwrite.
