How do I delete the automatic username suggestions on Facebook?

[highhair676]

On the homepage I was typing my username in and then I accidentally wrote my password in the same box, so if anyone else goes on Facebook (a.k.a my sister who likes to update my status to something rude every time she gets the chance) then they'll know my password.
Help please? By the way I use Internet Explorer 8.

i had the same problem. i found this: If you're using Firefox, it's as easy as highlighting the entry you don't want in the dropdown list (by pressing the down Arrow until it's highlighted with the dropdown list still visible) and pressing your Delete key. It'll remove it from the autocomplete list entirely.
