When FF on my Windows 10 machine crashed FF asked if I wanted to refresh FF. I said yes, and FF reopened as usual with all my tabs. After I closed and reopened FF the next time, it reopened without any of my tabs. I then discovered that FF had unchecked the “Startup Open previous windows and tabs” box, which I had previously religiously monitored to be sure it was checked. So I lost all my previous tabs.
In my sessionstore-backups folder I found the file upgrade.jsonlz4-20 as last in a list of three more recent file names. I then dropped the file upgrade.jsonlz4-20 in the scrounger tool on this site: https://www.jeffersonscher.com/ffu/scrounger.html. It expanded in the big window, and when I clicked on Save uncompressed JSON as text, I see all the URLs run together in a text file.
How can I use this information to recover my tabs, please? If so, how? Or is there a better way to use the Scrounger – or another – tool?
Otherwise if I delete the three more recent file names in the list above the upgrade.jsonlz4-20 file, and restart FF will I recover the missing tabs? If so would I the check or uncheck the Startup Open previous windows and tabs box?
Lastly, can I restore my missing tabs using Windows’ “System restore” tool from 3 days before the crash?
Many thanks for any help!
