I ran into the situation that I had accidentally a password pair registered for a webpage where I administer user accounts of a web site. From that moment on, I was unable to do the administration properly, since the name of the stored user always appeared in the fields, instead of that of the user I wanted to edit. This, in practice, the html-code said <input type="text" name="name" value="John">, but the screen showed "Tom" in that field. I suggest that, when a value is set in het html-code, the password manager would not be activated.
we have one for that...
This is a bug. A value is set for 'username' in the html, but the password manager changed it to the login name. Tested on mozilla 1.1 windows 98se. IE6 does not have this problem, so it is not the website's fault.
