My tabs failed to open after a Firefox crash. There is nothing else than a 2 kb file in sessionstore backups. Is there anything else I can do, or is all lost? 1200 is a lot, and those tabs hold great value to me. So I'm kind of desperate right now. Any help would be immensely valued! (I will start using a session backup plugin for sure.)

Suggestion: Bookmark anything you don't want to lose.


You may have corrupt sessionstore [v56] sessionstore.jsonlz4 file(s). Delete all sessionstore* files and the sessionstore-backups folder.

Type about:support<enter> in the address bar.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Locate the above file. Then rename or delete it. Restart Firefox.


Don't delete the files if you need to rescue any data from them, just move them out of the profile folder to some location where Firefox doesn't look for them. You can try to read out their contents using this tool: https://www.jeffersonscher.com/res/scrounger.html
