Does anybody knows why firefox sometimes restores to a previous session, like the one atleast a couple weeks ago, instead of the one I had when I closed it for the last time? and if I can do something about it, I tried using the files from sessionstore backup but they just update to the new session

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:

Hi Dany 00, did you back up the files from the sessionstore-backups folder? Since you just updated to Firefox 78 in recent days, the update snapshot might have most of your tabs. You can check it on my site here:


As for the larger question of why Firefox might use an older file, I imagine it's because there was a problem with a newer file -- such as being locked or corrupted -- but that's just a guess.
