Here's a complete example that works on FF2 and throws the above error
on FF3.

  <html>
    <head>
      <script>
        function crossFrameDomainXpath() {
 
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
          var d = frames['bottom'].document;
          var t = d.evaluate("//h1/text()", d, null,
XPathResult.STRING_TYPE, null);
          alert(t.stringValue);
        }
      </script>
    </head>

    <body style='margin:0px;'>
      <div height='35%'>
        <h1>h1</h1>
        This frame is localhost <br />
        <INPUT type="button" value="read xpath from bottom iframe"
onClick="crossFrameDomainXpath();"><br />
      </div>
      <iframe src="http://w3schools.com/xpath/default.asp" id='bottom'
name='bottom' height='80%' width="100%"> </iframe>
    </body>
  </html>

Any pointers greatly appreciated.
