JavaScript Window.Open location feature not working

Question

In my window.open I've set the location to no. As I understand it, this should open a popup window with no address bar. However, when the popup window appears it has an address bar in all browsers except for Safari. How can I open a new window without an address bar?

<script type="text/javascript" language="javascript">
$(document).ready(function() {

    var win = window.open("<%= Uri %>", "_blank", "directories=no,location=no,menubar=no,titlebar=no,toolbar=no,status=no");
    if (win != undefined) {
        window.location.href = '<%= this.Request.UrlReferrer.AbsoluteUri %>';
    }
});
