When closing Firefox, after reopening it, my tabs are gone, even though I have Firefox set to remember session. However, after several hours and opening and closings of Firefox, it will open tabs from the old session, for no apparent reason.

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox profile folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).


In case you are using "Clear history when Firefox closes":

  • do not clear the Browsing History

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, and passwords.
