for a day or so, this issue seems to have gone away. just as in the past, the tabs are there ready to use when i close firefox and reopen. maybe it was a "glitch" which is the most famous term in computerese.

I am going to mark this as solved and hope for the best. if the issue shows back again, I will start the search for fix again. thanks

You can try to restore the session stored in upgrade.jsonlz4-<build_id> in the Firefox profile folder.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).

You will normally find these files in the sessionstore-backups folder:

  • previous.jsonlz4 (cleanBackup: copy of sessionstore.jsonlz4 from previous session that was loaded successfully)
  • recovery.jsonlz4 (latest version of sessionstore.jsonlz4 written during runtime)
  • recovery.baklz4 (previous version of sessionstore.jsonlz4 written during runtime)
  • upgrade.jsonlz4-<build_id> (backup created during an upgrade of Firefox)

You can copy a file from the sessionstore-backups folder to the main profile and rename the file to sessionstore.jsonlz4 to replace the current file with Firefox closed.

  • make sure to backup the current sessionstore.jsonlz4

You can look at this tool to inspect a compressed sessionstore file.
