I play music from iTunes out of my laptop to my home audio system via the airport network I have setup in my home. In iTunes, there is a pulldown menu in the bottom right corner which enables you to select: computer or whatever airport base station it detects. How do I get the audio to play out of Firefox (or any browser) to the airport network similarly? I can't find such a selection in the browser preferences or Mac system preferences anywhere. Yes...you guessed right, I just discovered Pandora.
