Last week at IETF 83 in Paris Mozilla gave a little demo that went almost completely unnoticed. The team behind Firefox showed off an experimental built of its flagship browser with integrated WebRTC support. To showcase the real-time communication plug-in's capabilities, the foundation built a simple video chat client based around Persona and SocialAPI. Whether or not such a feature will ever make it into an official build of the browser remains to be seen, but for now you can check out the simple, yet impressive, HTML and Javascript demo after the break.
