Hi,

I shared a lot of important tabs to my laptop (using the firefox built-in share/send to other device button), upon starting it, they seemed to arrive just fine and opened on my laptop, however I accidentally clicked to "history"->"restore last session", which made this firefox window go away and all my sent tabs seem lost.

Is there any way to get them back? Any type of log?

I tried the following already: - Looking through History (they do not appear there at all) - Looking at recently closed tabs (there aren't any listed) - checking synced tabs window (did not contain the ones I sent from my phone to my laptop) - checked session recovery files ( none of my synced tabs seem to have gotten stored into that session recovery file)

So is there any other log or place I can look at? I refuse to believe that this is not saved anywhere? Or on mozilla servers at least? Can support help me?

Thanks for any ideas!

You can try to restore the session backup (upgrade.jsonlz4) Firefox created when you updated to 150.0.2 (or 150.0.1).

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

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

Hello,

You can try looking at the session restore backups : Cpse firefox, and if there are any lingering tasks in task manager, edn those too, then open your firefox profile folder %APPDATA%\Mozilla\Firefox\Profiles\, then open the sessionstore-backups folder. Find the recovery.jsonlz4 or previous.jsonlz4 files, then copy then and put the copy in a safe folder. go back to the main profile, and rename it to sessionstore.jsonlz4, and rename it to sessionstore.old. after that, copy the previous.jsonlz4 or recovery.jsonlz4 from the backup folder into the main profile folder and rename it to sessionstore.jsonlz4.

To prevent this from happening, Go to Settings > General > Startup and select "Open previous windows and tabs:

Hi,

Thank you both for the suggestions, I've already tried this with the website (https://www.jeffersonscher.com/res/scrounger.html) but it does not seem like those tabs got saved into any of those session files.

Is there any possibility I can get logs on sync side? e.g. mozilla server that "sent" the tabs to my device?
