I had a Firefox session open and had maybe 50 tabs open. I am not signed in and have the browser set to restore previous session every time it is opened. When I last updated the browser, my laptop crashed and turned off before the restore session had opened the previous window. When I restarted it, it was gone and I accidentally closed that window too. This meant the next time I opened it, it restored THAT session and not the one with all the tabs I had accumulated (but not saved or bookmarked). The problem is that some of those tabs had been there for a year or more so it's not possible to fond them in my history folder. Is there a way to restore a PREVIOUS previous session in Firefox or are they gone forever?

Hi Did Firefox managed to create an upgade.jsonlz4 in the sessionstore-backups folder?

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 try to restore the upgrade.jsonlz4 file from the last 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.
