This site requires a user name to be filled in a specific box and in another box you have to enter a series of numbers generated by a number generator (so not a password - different series every time you log in). However I don't want my username to appear automatically in the first box. When trying to change this in the security settings (extra-options-security), there is a password section where you can choose exceptions to the rule of remembering (if the remember box is marked). When clicking this exceptions box, the url of the site I'm talking about is not shown and it cannot be entered either, since you can only remove here. When clicking the "saved passwords" option, neither the site nor the username is listed. I think I have read all the help sections in relation to usernames and passwords, but found no solution. How do I prevent this username (so only a username - not the combination usename/password), to appear in the box?
