Firefox and Google Chrome support WebRTC, but currently Microsoft's Internet Explorer and Apple's Safari browser do not.
WebRTC will be on by default in Firefox 22, but the developers are still working out some kinks.
"What's great about WebRTC is that we can have true cross-platform communications that are vendor independent and work between mobile and desktop platforms," Mike Kaply, founder of Kaply Consulting, told TechNewsWorld.
However, true cross-platform communications might not be realized with WebRTC because Microsoft and Apple are not on board, and "I'm sure Microsoft will provide a competing standard that will be a different flavor of WebRTC," commented David Stein, a principal at the Stein Technology Consulting Group.
"There's core functionality, and then you have functionality that vendors have to use -- proprietary technology -- to deliver the functionality that users want to buy," Stein explained.
Firefox 22 is still evolving, and new features will continue to be added, Mozilla said. It's based on Gecko 22.
New Stuff in Firefox 22
Firefox 22 implements the HTML5 data element. Support for the multipart property on XMLHttpRequest and multipart/x-mixed-replace responses in XMLHttpRequest has been removed. Devs can use Server-Sent Events, Web Sockets, or inspect responseText from progress events instead.
PeerConnection and DataChannel, which enable P2P data sharing and video/audio calling respectively, have been added to Firefox 22.
For JavaScript, Firefox 22 has enabled Asm.js optimizations. Asm.js is a highly optimizable subset of Javascript developed by Mozilla that focuses on gaming, supercharging gaming code in the browser and laying the foundation for 3D Web-based gaming on mobile devices.
