I just restarted Firefox and, much to my distress, the tabs are now as they were on May 27th (I know this because that is the date in one of the tabs). This means some tabs are open that I closed in the last seven weeks, and all the tabs I opened and kept open in the last seven weeks are gone (in this case all my research). The information is there in history but it would take me hours to reopen all the hundreds of research tabs I opened in the last weeks and then close the ones I already closed as I no longer need them.

Why has it done this? How do I keep it from doing this again? And is there a way to force it to open with the tabs I had open just a few hours ago?

Thank you!

This could be a problem with sessionstore.jsonlz4 in the Firefox profile folder.

You can try to restore a recent upgrade.jsonlz4-<build_id> when available or use a utility to browse Windows System Restore points to see if you can find a recent sessionstore.jsonlz4 file.

You can look at this tool to inspect a compressed jsonlz4 sessionstore file.

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 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).
