When I go to a website that requires user-name & password I enter them and then Firefox pops up "do you want firefox to remember your user-name & password for this site". I made the mistake of clicking "yes" and now when I go there the site comes us with both. I have several user names & passwords for some sites and now I don't want firefox to remember them. So, how do I reverse my decision to have firefox remember and display my user name and password for a particular website?
