How do I change the setting that remembers which user names are typed within the user name tabs of given websites?
When I am typing in my user name for a website, a bunch of previously typed user names pop up. I Do not want those other names to pop up, and/or I just want my own user name to appear when I begin to type it.

When the unwanted name pops up and is highlighted hit the delete key on your keyboard and it will be removed and not pop up again.
