After Firefox was accidentally shut down, a program re-opened it and now the previous session can't be restored. I need to see the tabs I had open in the previous session. I have a upgrade.jsonlz4-build_id file that I can restore to an earlier point that will have that info.

Can you please give me step-by-step instructions on how to restore the upgrade.jsonlz4-build_id file?

Thanks!

Hello engetka!

I think that this question may provide you the solution to your issue: Restore previous session from session backup

Then again I may have misunderstood your exact question - in that case please provide a bit more details.

Best regards, Boneff
