Windows 7, firefox 40.0.3

My computer crashed and thus, firefox did not close properly and lost all of my tabs. Under Menu -> History, the Restore Previous Session is greyed out. Why is this? Shouldn't I be able to restore from there?

I've found replies from "jscher2000" and my sessionstore-backups\previous.js file looks like the one I want to use to restore my tabs. However I do not see how to use this file to restore my tabs.

How do I use previous.js to restore my tabs and tab groups?

You can backup the session files in the sessionstore-backups folder in the Firefox Profile Folder to make sure not to lose possible important session data. You can find these files in the sessionstore-backups folder: 

previous.js (cleanBackup: copy of sessionstore.js from previous session that was loaded successfully)
recovery.js (latest version of the sessionstore written during runtime)
recovery.bak (previous version of the sessionstore written during runtime)
upgrade.js-<build_id> (backup created during an upgrade of Firefox)

You can copy a file from the sessionstore-backups folder to the main profile and rename the file to sessionstore.js to replace the current file (make a backup copy of the current sessionstore.js).

You can use this button to go to the current Firefox profile folder:
