I've always had my "Open previous windows and tabs" setting on and its never failed for me but today I opened Firefox and it none of my previous windows opened, it just opened to a blank window and I've tried to recover my previous sessions but my "Recently closed windows" tab in history won't open. Not really sure what to do here as I would like to have my previous windows since I didn't bookmark them which I probably should've done

Did you try Restore Previous Session?

Backup the session files in the sessionstore-backups folder in the Firefox profile folder to make sure you do not lose possible important session data. Do NOT close Firefox when Firefox is already running.

You will normally find these files in the sessionstore-backups folder:

  • previous.jsonlz4 (cleanBackup: copy of sessionstore.jsonlz4 from previous session that was loaded successfully)
  • recovery.jsonlz4 (latest version of sessionstore.jsonlz4 written during runtime)
  • recovery.baklz4 (previous version of sessionstore.jsonlz4 written during runtime)
  • upgrade.jsonlz4-<build_id> (backups created during a Firefox update)

You can copy a file with Firefox closed from the sessionstore-backups folder to the main profile folder and rename the file to sessionstore.jsonlz4 to replace the current file.

  • make sure to backup the current sessionstore.jsonlz4

You can look at this tool to inspect a compressed jsonlz4 sessionstore file. This tool works locally, no uploading is done.
