Tried to fix slowness, freezing up. Logged off, now get a message "the user profile service failed the logon. User profile cannot be loaded".

If the user profile can't be loaded, it's a system error, not a problem with Firefox. Unfortunately, if you can't log in, I don't know how you would fix this.

Start by booting in safe mode and uninstalling Firefox if you feel that's the cause. Otherwise, also try using System Restore and see if that works.

And how does this pertain to Firefox? (Sorry, I just don't see the connection.)

No problem until I followed instructions to fix Mozilla, logged off and attempted to log in the next day.
