The quest to free the browser from plug-ins that can impede performance took another step forward on Thursday when Mozilla activated by default Web Real-Time Communication in its latest Firefox beta.
PeerConnection lets the browser set up real-time video and audio calls, while DataChannels enables peer-to-peer data sharing during a call. That data can be just about anything, including text, video files, and HTML pages, and it can be shared using standard drag-and-drop techniques. Mozilla noted in its blog post about WebRTC in Firefox that DataChannels can be used by gaming apps to reduce latency during peer-to-peer connections.
Coming improvements to WebRTC in Firefox include TURN support, which will allow WebRTC to work with firewalls, and Android support, although it's not clear yet if those will arrive before WebRTC lands in the stable build of Firefox in about six weeks.
