Add webidl interfaces and implementations of the HTML <track> element and related TextTrack, TextTrackList, TextTrackCue, and TextTrackCueList dom objects. Visibility is controlled by the media.webvtt.enabled pref, which defaults to false. HTMLMediaElement:NewURIFromString() is hoisted to nsGenericHTMLElement so it's available to the track element as well. This patch is primarily work by Dale Karp, David Humphrey and others as Seneca College.
