After my virus checker interrupted Firefox as it was opening (to remove a "telemetry" add-on or something), I reopened Firefox to find it would now only restore three of the ten windows from the previous session.
Obviously I would like to get back those other windows if possible. After some fiddling around, I opened my "sessionstore-backups" folder and discovered both the "recovery.jsonlz4" and "previous.jsonlz4" files contained the recent incomplete session rather than the older one I wanted.
I figure my last hope at recovering some of my lost tabs is the file "upgrade.jsonlz4-20180830143136". Am I right in thinking it can be used as a restore point? I have tried renaming it to "recovery.jsonlz4" while deleting the more recent "recovery.jsonlz4". Yet for some strange reason, when I restart Firefox it keeps going back to the deleted recent session file.
I have been copying the more recent "recovery.jsonlz4" to my Data drive before deleting it from "sessionstore-backups" - could that be causing the problem? It's in the Recycle Bin too. I'm just reluctant to delete it entirely.
In short: Why does Firefox keep restoring a session I've deleted? How can I make it restore the older upgrade file?
