I feel like I'm in the Twilight Zone. I uninstalled Firefox from my current user (Admin rights). Then I went into two of the three users I have and deleted the Mozilla folder from Appdata directory. The last user, Admin rights also, won't allow me to do that because I need admin rights, even when I'm logged on as that user, which has admin rights.
Then I reinstalled FF. I went through the Mozilla support page steps to add a profile. It worked!!.... once. The second time I started it the program went non-responsive again. I did it again. Same thing. I rebooted, same thing: works once (meaning it loaded saved tabs) and not the second time (meaning just blank tabs and the endless circle turning). Rebooted. Works once and not the second time.
Uninstalled FF and all private data again (saved profile from my old rig in 7z file). With no attempt to change profile I've started FF four times now with saved tabs on a clean new profile.
FF is available to user 2 but not to user 1, the contaminated one, the one that won't allow me to delete the Mozilla folders. It still had FF icons on the taskbar and desktop but they don't do anything, even though FF is installed through user 3.
So I deleted user 1 account. Then I copied old profile to profiles folders. I tried running 'firefox -p' in the Run window and FF the browser started, not the profile manager. What gives? I'm doing everything the Mozilla site says and my rig does things differently. A two week old rig.
Then I edited profiles.ini to the name of the old profile. Crashes again. Reboot. Works once, crashes on the second opening of the program.
What am I doing wrong? I've spent almost 50 hours trying to get this machine to be workable. I thought I'd done okay by establishing a new Admin user account and deleting the contaminated one.
There seems no way to get my old profile into FF so that I can use it, at least not with the info on the Mozilla site. Or am I not implementing it correctly? Should I wipe the disk and start over?
