Web browsers are becoming more and more like operating systems as web pages become more and more like apps. The idea of a browser-based operating system like Chrome OS doesn’t look as silly as it once did now that you can play games, edit documents, participate in video chats, and do much more in a web browser.
Firefox supports the new WebRTC, or Web Real-Time Communications protocol which allows app developers to create websites that can securely use your computer’s camera or mic to make video calls without users having to install a custom plugin.
Chrome already supports WebRTC, but the point here isn’t so much that one team beat the other to the punch as that now there’s a better chance you’ll be able to make use of new web apps no matter which browser you’re using.
You can check out Mozilla’s BanaBread demo to test a multiplayer 3D first-person shooter in the latest version of Firefox (it runs pretty well on Chrome OS too).
There’s also a new version of Firefox for Android, but it doesn’t yet support WebRTC or asm.js. It does offer support for the full tablet UI on tablets with smaller screens, improved WebGL performance, and a few other fixes and improvements.
