When I log into a particular website, two user names appear just below the user name box, one of them is incorrect, the other one is correct. The correct one is stored in Firefox settings, the incorrect one is not stored there. Where could it possible be stored in Firefox so I can delete it. The fact that it is shown on the log in page of this website requires the website people to make me change my password every week. They say I must do that for security reasons because I have two usernames showing when I log in, and that I must remove the one that is incorrect. They they won't make me make a new password every week.
