(Since I don't do this daily, I guess it's not really "tip of the day" but why quibble over the details ;-)
If you're like me and you don't use bookmarks very often, instead relying on bookmark keywords and address autocompletion, this tip is for you. When you get bogus items in your Firefox address autocomplete list, you can easily delete them by just arrowing down to the bogus one and hitting shift+delete on your keyboard. Cleaning up your address autocomplete for common sites every once in a while will make your browsing experience more pleasant.
