Lost open tabs and cannot recover them

I was trying to change some settings on Firefox and I accidentally closed it and lost all of my tabs. I have the setting enabled to open tabs from last browsing session, but I was messing with the extension OneTab and I lost my open tabs.

Just to be clear, it wasn't the fault of OneTab, this is was my fault for closing Firefox too quickly when it was restoring my tabs and I didn't allow it to finish.

Anyway, in attempting to recover my tabs, I have restored from backup my "sessionrestore-backups" folder; this didn't work. I have also restored my entire Mozilla folder in my profile; this also didn't work.

I also tried following this article (https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup), but the sessionstore.jsonlz4 file doesn't exist. I did a search for this file in my profile and it doesn't exist anywhere.

Does anyone have any ideas that may help?

Thanks in advance!

I was able to fix this issue myself.

I had to delete all of the files in this directory first, then do the restore. Restoring the files with overwrite was not enough, I had to delete everything first. Then when I did the restore it all worked fine.

I think this is probably a common occurrence and filed a bug that can hopefully be addressed: https://bugzilla.mozilla.org/show_bug.cgi?id=1873400
