Firefox 28 debuts with an emphasis on under-the-hood improvements to keep the browser in line with the latest plug-in-free media playback tools.
They're not exactly another nail in the coffin for Flash, since Firefox already offers broad HTML5 media playback support, but they do signal that plug-in-free codecs are maturing into broad usability.
Unfortunately for Windows 8 users, Mozilla decided to mothball the Windows Metro mode for Firefox just before this update. Mozilla cited the incredibly low daily usage figure of only around 1,000 people per day as the reason behind the decision.
Firefox 28 for Android sees more of the same, with VP9 decoding, WebM with Opus, and HTML5 audio/video controls. It also received some interface tweaks, including an option to toggle the automatically disappearing "Awesomebar;" more quick share buttons, automatic predictive search in the Awesomebar; and adjustments to the text selection, copy, and cut options to make them feel more native to Android.
