I had a power brownout and my PC rebooted. Once I logged in again and restarted Firefox I got the restore session window with all my windows and tabs. Unfortunately before I could hit restore another brownout occured and this time when I opened Firefox the restore window did not show up. Is there anything I can do to get all my open windows and tabs back? They have been open for a while and all from different dates so it would be an enourmous task to go trough all the history. Thanks
