    mozbrowsermetachange

    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 mozbrowsermetachange event is fired when a <meta> element related to web applications is added, removed or changed.

    See below for the applicable types.
