How do I delete usernames from a drop down list?

[scrappydappydoo]

I wasn't paying attention when logging onto facebook and accidently typed by password after my username and presses enter. Now the drop down list displays my username and password. IYKWIM?? If you do then how do I get rid of it??? HELP!! I know its probably something really simple but I can't figure it out!

bump!!

Please (getting desperate!)

click in the box when empty. Press the down button on your keyboard (you might have to type the first letter of your username first) and when the one you want is highlighted just press delete on your keyboard :)

Delete your history and the cookie for Facebook.

delete your browsing history and cookies. tools, internet options, delete temporary file and check box to delete history on exit.

I was lurking as I had a similar problem. BertieBotts your suggestion worked for me - thanks.

Thank You!!!!!
