Previously the 'well this is embarrassing' homepage would give me the button to restore old tabs.

Recently a crash window had given me multiple options for which session to restore and I was choosing the most recent one.

Overnight I think my laptop restarted - This morning for some reason no session restore is available at all - and I went to look at the history tab and it's greyed out.

I have gone on the help here to try and find a solution and located in the Firefox profiles folder 2 sub folders sessions and sessionstore-backups but the files can't be opened on windows? The jscript script files 'previous' and 'recovery' pop up a window that says windows script host error code 800A03EC and windows can't open .BAK files or SESSION files

Please help I had like 90 tabs open and some have been open for ages, I need them back!

You can open such a file in the Scratchpad (Firefox/Tools > Web Developer). Click the "Pretty Print" button to format the file for readability.

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. 

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).
