Mozilla has updated its web browser “Firefox” to version 28.0. It comes with new features and updates.

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.

Firefox 28 for desktops also gets a new volume control for HTML5 audio and video.
