Chrome Frame: Access is denied error in IE9

Question

I am attempting to use Chrome-Frame on a site I'm building. In IE8 and below, everything works fine... In IE9 I get this error:

SCRIPT5: Access is denied.
cf-dlpage.js, line78 character 209

No idea what to do!

here is the conditional that is triggering the behaviour:

<!--[if lte IE 9]>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/chrome-frame/1/CFInstall.min.js"></script>
  <style>
        body {
            overflow-y:hidden;
        }
      .chromeFrameOverlayContent {
            border:none;
            overflow:hidden;            
        }
      .chromeFrameOverlayContent iframe {
            border:none;
            overflow:hidden;
        }
      .chromeFrameOverlayCloseBar {
            display:none;
        }
      .chromeFrameOverlayUnderlay {
            background-image:url(/img/bg.png);
            opacity: 1;
            filter: alpha(opacity = 100);
        }

  </style> 
  <script type="text/javascript">
    window.onload = function() {
        CFInstall.check({
            url: "/fix/update.html",
            mode: "overlay",
            destination: "/"
        });
    };
  </script> 
  <![endif]-->

Any help greatly appreciated!

Answer 1

Try this it sounds that its related to your problem. i hope it helps. read comment from erikwright@chromium.org, is the last comment right now.

Answer 2

The problem is caused by this:

1. Your page is on www.example.com
2. The installation routine creates an iframe with a url www.google.com/...
3. The iframe page itself executes Javascript and tries to read window.parent, but...
4. ... this is not allowed because both frames have different domains.

The only solutions seem to be:

1. Create your own install script
2. Google fixes their script

I wasted a whole day trying to work around this problem (nested frames, custom scripts, routing Google requests through my server,...) until it dawned me why Google seems to ignore this bug:

Most people simply don't notice the problem. The installation is performed successfully, regardless of this error. To actually get a message box you have to enable Javascript debugging or the Show Javascript errors feature.

You and I have enabled said features because we are developers, so naturally we freak out, but Average Joe won't notice anything.
