i tried settings in browser (Firefox 23.0.1) auto fill, clearing cookie, and other steps to fix this that haven't worked. once months ago when logging into my gmail acct (on work computer) i accidentally didn't hit tab after entering my gmail acct name before entering my password, so my entered acct (user) name was my gmail address AND password. . now everytime i go to log in again auto fill or something suggests my regular login name plus the password - pretty unsecure for work!!. how can i delete the auto fill prompt?
