I recently updated my main desktop browser to the latest version (62), but for some reason this caused the name of the device to change. What used to be "<Name>'s Firefox on Desktop" is now "<Name>'s Firefox on <Name>". I had only realized this happened since none of the tabs I sent from my work computer to my desktop were appearing.

1) Are all of the tabs I sent now lost? Is there a way to recover these tabs? 2) If I rename my desktop computer back to its old name, will the tabs finally arrive? 3) How do I resync all of my devices with the correct device names in all lists?

Something to note, the old device name no longer appears in the "manage devices" list even though it is still present in the right-click menu of the "send tab to device" list.

Computer name doesn't have anything to do with FF tabs those are two separate programs. Desktop is a O/S function and tabs are a Browser functions.

I never said that the computer name has anything to do with FF tabs. The computer name is not a program, it's just an identifier. The desktop is a folder on your filesystem and tabs are not necessarily "browser functions".

Please read the post next time instead of posting random, unhelpful comments.

Thanks.

You can check if there is a recent upgrade.jsonlz4-<build_id> file in the sessionstore-backups folder that you can use to recover the lost sessuion.

Note that Sync isn't meant to be used as a backup, but is meant to sync data across multiple devices.

Firefox uses the sessionstore.jsonlz4 file in the profile folder to store session data. The sessionstore.jsonlz4 file is only present when Firefox is closed. The sessionstore.jsonlz4 file is created from recovery.jsonlz4 when you close Firefox and is removed and copied to previous.jsonlz4 when you start Firefox to make is possible to restore the session at any time.

Backup the session files in the sessionstore-backups folder in the Firefox Profile Folder to make sure not to lose possible important session data. Do NOT close Firefox when Firefox is already running.

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 (make sure to backup the current sessionstore.jsonlz4).
