You can check the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] to see if you have a file sessionstore.bak from the date and time that you had that crash. If you have that file then make a backup copy of it and rename the file to sessionstore.js. See http://kb.mozillazine.org/Session_Restore --- See also http://kb.mozillazine.org/Firefox_crashes and [[Firefox crashes]] .......... If you have submitted Breakpad crash reports then it might help if you post the IDs of one or more Breakpad crash reports. You can find the IDs of the submitted crash reports on the ''about:crashes'' page. You can open the ''about:crashes'' page via the location bar, just like you open a website.
