    I feel this is because of some security. You can try this way instead:

    <html>
<head>
    <title>Parent</title>
    <style>
        div {
            float: left;
            cursor: pointer;
        }
    </style>
    <script type="text/javascript">
        var SubpopUpWin = "";
        var testUrl = "";
        function Opennew(passedURL){
            testUrl = passedURL;
            SubpopUpWin = window.open("popups.htm", '_blank', 'toolbar=no,status=no,menubar=no,scrollbars=yes,resizable=yes,copyhistory=yes');


        }
    </script>
</head>
<body>
    <div onclick="Opennew('http://www.google.com')">
        Google
    </div>
    <div onclick="Opennew('http://www.yahoo.com')">
        Yahoo
    </div>
    <div onclick="Opennew('http://www.bing.com')">
        Bing
    </div>
</body>


    <html>
<head>
    <title>Child</title>
    <style>
        div {
            float: left;
        }
    </style>



</head>
<body>
    <div>
        <div id="ifrm_title">
        </div>
        <div style="margin-top:20px">
            <iframe id="ifrm" src="" width="470" height="270" frameborder="0" style="margin-top: 34px" scrolling="no">
            </iframe>
            <script type="text/javascript">

        document.getElementById("ifrm").src = window.opener.testUrl;

    </script>
        </div>
    </div>
</body>
