I always have many tabs up, and I just used them this morning. Now I've opened my computer and everything is gone. I tried to look for any option to restore the previous session, but the option isn't even showing up. This is weird bcuz my computer is working fine, and I set 'always restore session' as my preferred option. Can anyone help?

. . . and everything is gone.

Are you just talking about just your sessions? What about the rest of your profile? Settings, bookmarks, history, passwords . . . .


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
