Closed tabs keep reappearing, either spontaneously or on Firefox restart. Trashed the session files, emptied the trash, even restarted the computer to no avail. It will even create duplicate tabs of these same five tabs that were closed days ago. Thank you in advance for your help.

Firefox 78.15 running on mid 2007 iMac, El Capitan version 10.11.6

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

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
