After reboot, all my tabs & tab groups were gone.

I rebooted my HP desktop computer, then reopened Firefox. I had 3 separate tab groups with lots of tabs in them, but everyone of them was gone. I closed the FF, then reopened it again (hoping this might correct it), but no change. I tried the restore previous session in History, but it just gave me what the previous one had - which weren't my tabs.

I worked hard to collect these & I want them all restored. Just because I rebooted shouldn't cause me such trouble!

Hey serenanocturna,

First off, do you have Firefox set to restore tabs from previous sessions ?

You might also want to try recovering your sessionrestore.js file. Take a look at the info provided by cor-el in this thread for details: https://support.mozilla.org/en-US/questions/941352
