It was only a few weeks ago that Chromecast support was spotted in Firefox for Android's nightly builds -- now it's one step closer to primetime: the feature is now a standard part of the browser's beta package. This means that Mozilla fans eager to stream from their favorite browser can access the experimental feature from Google Play, rather than manually installing the update. It gets better, too: the official beta also has support for Roku streaming, assuming your set top box has the Firefox channel installed. Finally, Mozilla quietly announced that its bringing WebRTC support into the main beta channel of its desktop browser. All of these features are still in their early stages, of course, but if you want a sneak peek at what's next for Mozilla's stable releases, the source links are below.
