Sounds like you've hit bug 351551 before the latest update and are now still suffering of its consequences. To fix that issue, you'll have to go to your profile folder <http://support.mozilla.com/kb/Profiles#Profile_folder_locations> and delete all files named sessionstore-#.js (where # is a number between 1 and 9999). If that was indeed the problem, please close this bug as WORKSFORME.
