address box in global options screen lets you enter anything

[jawz101]

if I type any alphanumeric character in the address box and hit the plus sign, the whole list does some animations and then a new item is added. I added "1" as an address, "a", "http"... Now I don't know how to delete them.

Set them to Default, and they will be gone the next time you load the Settings page.
