Non-standard
This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.
The mozbrowsericonchange event is sent when a new icon (e.g. <link rel="icon"> or <link rel="apple-touch-icon">) is available in the browser <iframe>'s content.
It will be fired once for each icon available.
