Firefox updated on my work machine concurrent to a machine self-restart and VPN update. The VPN update bricked my access to shared drives for my work network so I assumed the issue lie somewhere with lack of internet access and inability to connect to said network. Now the VPN is up and running with normal file access restored, but all my FireFox info is gone. I see on my desktop a file called Old FireFox data and begin googling the recovery process. I generated a new profile in FireFox and copied over all files from the old profile to the new including key4.db and logins.json to no avail. There are no passwords, no login info, no cookies, no bookmarks, nothing is left. Also, I cannot copy any of these files. I can only move them for some reason. I've tried to back up these files, but they are move-only somehow. Any advice?
