So I've been beating my head against the wall on this one... first I couldn't load Firefox and the error message would say 'Firefox is active but not responding.' I looked into that, it suggested deleting the profiles.ini file... I did, and it didn't do anything. I then tried deleting the profile folder entirely. That changed the error at least. Now it says 'no profile.' So, I tried following directions to create a new profile. Win+R, firefox.exe -p and then tried to create a new profile and... nothing. "An unexpected error has prevented your changes from being saved." Unsure if its connected, but at the same time, several Steam games have been struggling to sync to the cloud, and Discord stopped working to the point I needed a clean install. Already tried to do a clean install with Firefox and that didn't work either.
