It been now the second time that upon opening firefox, it doesn't open the previous session but a new one. It's the second time that I loose ALL my tabs. The "restore previous session" is greyed, I tried the about:sessionrestore but it doesn't give me the possibility to restore the previous session, and on my computer, the sessionstore backup just has the restoresession from today. Is there any way to avoid this?

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

Thanks, I think that might have solved it, Firefox reopened on a new page, but then it recovered the previous tabs (not the ones from the previously lost sessions however)

Glad to help. Safe Surfing.
