I had to force quit Firefox and when I reopened it, there was no option to restore the previous session. I have looked through the previous questions about this and it talks about looking for a sessionrestore.js file, but the only one I get when I search in Finder is in a file called "Old Firefox Data." I did a backup using TimeMachine not too long ago. How can I use that to restore the last session backed up on the external drive? Also, if I do, will that wipe out my history? I'm hoping to get the more recent tabs I had opened from the history and therefore get close to where I was. Thanks!

Okay, I finally found my profile after much trial and error while searching. I have no idea why it wasn't easily found. There is a recovery.js file in the sessionstore-backups folder. How do I use the file from TimeMachine to get my tabs back? Thanks for the help!
