I had a lot of tabs opened for months now but this has happened before when I was able to restore the tab history in the profile folder in firefox with the "sessionstore.js" file and look up previous versions that were available. When I exited firefox and did a restart on my computer all of a sudden when it came back on it didnt restore the session I had previously opened. I went to the profile folder and tried to look up previous versions of that sessionstore.js file and the bak file too and it said it was no previous versions available. How can this happen all of a sudden when I exited and restarted the computer? I have Firefox set to remember the history and tab history and session restore to restore it all but yet this mess happens. Can anyone guide me into what to do for other things that can restore this session in Firefox because I know I didn't loose this for nothing and It has to be somewhere to restore all my tabs back. Any help?

Awesome, glad you know about that Previous version trick.

There's a catch though. It never works for me if you check for previous versions on the individual Firefox files. You have to check previous versions on the actual firefox profile folder.

So to view the folders, navigate to where your Firefox profile folder lives: C:\Users\[Username]\AppData\Roaming\Mozilla\Firefox\Profiles\[random].default\

Right-click on the [random].default folder and choose Restore previous versions. Choose a folder dated from before this accident and click the "Open" button. You should find a safely backed up sessionstore.js file there. ;) Lastly, copy the file to another safe location and copy it back into the Firefox profile.
