Can I restore my previous browser session with the "previous" file in "sessionstore-backups"?

I opened my browser like usual, but a program interfered before I clicked on "Restore previous session" and closed the browser. When I opened my browser again, the option to restore the session was gone. I read in other posts that you could restore these sessions by using "sessionstore.bak" or "upgrade.js-(datetime)" in the "sesstionstore-backups" folder. However the file that corresponds to the session I want to restore is called "previous". Is it possible to restore that file as a session, and if so, how can I do it? Thank you in advance.

Make sure to create a backup of all the files in the sessionstore-backups folder. You can copy the previous.js file to sessionstore.js in the main profile 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)
