Note Firefox's ''sessiorestore'' sytem tends to be slightly fragile. Try not to over rely on it. At least ensure any important open pages are bookmarked. '''''Firefox sync''''' may help but that is also rather trouble prone. Firefox sync may improve in Firefox 29 with the new Firefox accounts, but personally I would not rely heavily on that either. Firefox sync may also scramble bookmarks so make sure you not only bookmark but also make manually backup your bookmarks. * [[Restore bookmarks from backup or move them to another computer#w_manual-backup]]'''_manual-backup''' *[[How do I set up Firefox Sync?]] **[[How to update to the new Firefox Sync]] As for the lifesaver, the easiest method is to open the profile from the option in the troubleshooting information page of a running Firefox. Then close Firefox and find the files to copy. *[[Use the Troubleshooting Information page to help fix Firefox issues]] ** [[Profiles - Where Firefox stores your bookmarks, passwords and other user data#w_how-do-i-find-my-profile]]'''_how-do-i-find-my-profile''' Note that Windows does not always display the .js extension filenames you may need to check the Windows options are set to display filename dot extensions. * http://kb.mozillazine.org/Sessionstore.js
