    mozbrowsercaretstatechanged

    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 mozbrowsercaretstatechanged event is fired when the user selects content in a page loaded in a browser <iframe>. This is used by the embedder to show a context menu for clipboard actions.
