If you open the task manager, is firefox.exe running as a process? If so, this is most likely caused by an extension. Do you have ghostery installed? Can you please test in safe mode? http://support.mozilla.com/en-US/kb/Safe+Mode
Check if more than one version of Firefox is installed. Uninstall any old versions that you do not use. If you want to retain more than one version you will have to use Task Manager to end "firefox.exe" under Processes.
This appears to be a problem with Firefox quitting (and likely is due to an extension), not a session restore problem.
Please read http://support.mozilla.com/en-US/kb/Firefox hangs#Hang_at_exit and reopen this bug only if you are sure that this isn't caused by an addon/plugin. You can use the support Forum if you need more help
