This is my original post. No response at all. Disappointing.

Non functioning Export/Import, upload images

At this point, if I could just get an opinion, a direction you might follow, if this was happening to you

It keeps recurring. This time it took 3 weeks from the time that last post. As I said in the past post, the problem is a corrupted 'sessionstore.jsonlz4 file.

My evidence is that when i ran about:support - Troubleshooting, the problem was still happening.

I just mounted a backup profile, created during the last incident. Works fine. I took the sessionstore.jsonlz4 from that backup and replaced the one in the problem profile.

After doing the replacement, the problematic profile symptoms have disappeared. At least for now, that is.

But now, I have to restore the missing portion of the session (tabs/history) created between the last occurrence and now, because of the replacement of the corrupted sessionstore.jsonlz4 with the backup.

Nobody has offered a way to do this that is not a time consuming ordeal.

What would you do?

You can look at this tool to inspect a compressed jsonlz4 sessionstore file. This tool works locally, no uploading is done.


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> (backups created during a Firefox update)

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

  • make sure to backup the current sessionstore.jsonlz4

I'm now experience numerous symptoms in terms of broken operation.

I've always been confused about syncing sessions. Does one profile take precedence over the other, as in will it replace the session of the other pofile with it's own, or will the two sessions combine?

As I mentioned, I believe sessionstore.jsonlz4 has been altered in some way that is at least partially responsible. Is there any chance these problems will be passes along?

Maybe someone could direct me to a place where I could get detailed sync info?

I just wanted to mention that the problem with the sessionstore-backups folder contents is that if you don't recognize new breakage right away, any good backup files will automatically be replaced by infected ones. But as I mentioned, even replacement is made from other backup profiles, that never exhibited the problems in the past, the problem eventually recur.
