    mozbrowsershowmodalprompt

    This article is in need of a technical review.

    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 mozbrowsershowmodalprompt event is fired when the content of a browser <iframe> calls the window.alert(), window.confirm(), or window.prompt() methods.
