I need to recover a lost tab group. I'd like to restore my previous session, but I don't know if I can.

I have not yet exited firefox, as per https://support.mozilla.org/en-US/questions/1028115. An update took place tonight, but I'm not sure if that caused my problem. It seems as if all the sessionstore.js files are old, so they probably won't help. There is an upgrade.js file that has the right time and date to be helpful, but I don't know how to implement it to restore my tabs. I tried to open it, it asked which program and I said firefox, and it opened in a tab as a giant text document, which does seem to have the information I need. There is also a previous.js file that has the right date and time. This is ridiculously frustrating not having the slightest clue how to proceed, so any help would be greatly, greatly appreciated!

hello, first of all please create a backup of all the involved files in a safe location!

you can then apply one of the sessionstore-backups (for example upgrade.js) if you copy it to the main profile folder and rename it to sessionstore.js replacing the file with the same name that is already there while firefox is closed. afterwards start the browser again...

Thank you so much man, you're the greatest! I ended up using previous.js because I think I screwed up the upgrade.js file when I chose to open it with firefox, and that worked perfectly.
