I've just been watching this IO talk on WebRTC, so it's certainly possible in Chrome and Firefox. https://www.youtube.com/watch?v=PMH1vM-dSc0

It actually does use WebRTC in Chrome. It falls back to Flash in FF right now.

Why? Firefox has had WebRTC support for a while.

Edit: Ok I see below you want Firefox to give you access to the users microphone without asking permission.
