I tried the steps to fix the "Firefox profile missing" error, but it's not solving the problem.

I have tried multiple times ending any Firefox processes in the windows task manager, but when I try to open Firefox it still says my profile is missing. I've tried looking around more but I don't know why this won't work. It's just a never-ending process basically.

Hello Gen10, did you try to delete (or rename, for example, to profiles.iniOLD) the profiles.ini file ?

see in the next link at "Profile was deleted" area, the Method 2: Manually delete the profiles.ini file, any luck ?
