My school website required users to change login passwords to conform to stricter security standards. Login credentials used to autofill, but now they don't. I've been dealing with this issue for awhile now, but I think what I did was to remove the login credential information from Mozilla. It never asked me to store the new password and I can't figure out how to get it to autofill again. The site is not in the exceptions list and when I view site information, under the Security tab, where it lists "Have I saved any passwords for this website?" the answer is "No."
