I'm not sure if you can do this in other operating systems (too lazy to find out), but, in Vista, you can just turn down the volume for Firefox, but still have another appplication's volume unaffected (Media player, Zune, etc.), so it doesn't really need a mute button.
I love all the people commenting about the second challenge. For all you still wondering, for challenges like this, where its sponsored(in this case, by Axe), they don't usually put it on a new game, and they also usually put it on one of the highest rated games, so it will probably have had a challenge before.
