Yesterday I mentioned Microsoft's Soccer Scoreboard. If you prefer to take your sports scores in the form of a Firefox extension, there's FootieFox, an extension that will give you up-to-the-minute scores for today's matches. You can configure it for your preferred teams and leagues, and it will sit quietly in your Firefox statusbar displaying the most recent score, or all matches at the click of a mouse. It even has visual or audio notifications for when your team scores a goal.
