Firefox Nightly for Android now casts videos to Roku – Liliputing

When you encounter a website with an embedded HTML5 video encoded in H.264, Firefox should detect the video and detect the Roku on your WiFi network and bring up a media control bar with play and cast buttons. Hit the cast button (which looks just like the button you’d use to send video to a Chromecast) and the video should start playing on the Roku. You can then pause, play, or close the video from your phone. The video bar will be visible as long as you’re using the [Mozilla Firefox] browser, even if you open a new website or switch browser tabs. – Brad Linder, Liliputing
