Firefox 22.0 Final available for download

Mozilla has released the Final version of Firefox 22.0. Firefox 22.0 includes WebRTC (Web Real-Time Communications) capabilities to enable developers to easily integrate real-time communications, including voice and video calls and file sharing, across the Web.

Release Highlights
Firefox 22.0 includes WebRTC components, PeerConnection and DataChannels, on by default. PeerConnection allows the Firefox browser to set up real-time audio/video calls, and DataChannels allow browsers to share almost any kind of data (text, video files, html pages) peer-to-peer, either during or outside a video call, for example, by dragging an item into a chat window. WebRTC allows developers to test WebRTC much more widely than before because Firefox users won’t have to enable WebRTC in their preferences.
