Auto fill - browser fields

Sometime long ago my konqueror stopped suggesting choices for filling in userid fields in web page login forms. I've poked around a lot, but cannot see how to (re)activate that. On the same topic: Is there a way to delete an inappropriate auto fill item? And, being greedy, does anyone know the same answers to these questions vis-a-vis Firefox and Chrome?
