Return message on window.onbeforeunload custom message didn't set. it shows always default message

I had tried to return my custom message to onbeforeunload confirm box, but default message didn't change what I sent.

    window.onbeforeunload  = function (event) {
        event.preventDefault();
        return 'You are leaving this page. Please confirm or data will be lost';
};

This Changes worked on Firefox 46.0.1 enter image description hereenter image description here

according to MDN's browser compatibility chart for this event, custom text support has been removed from newer versions of Chrome and Firefox. If you're using FF >= 44.0 or Chrome >= 51.0 , you'll get the default window-closing text instead of your own.
