I was also getting the same error.

To overcome this error I used the following line of code:

alert(document.getElementById('external-site').contentWindow.document.location.href);

Since all you want to do is 'check' if it is external, why not catch the error? Seems to work in FF and Chrome. See jsFiddle.

try {
    alert(document.getElementById('external-site').contentWindow.location.href);
}
catch (err) {
    alert("undefined");
}

if document.getElementById('external-site') is referring to an iframe which is loading a page from a different domain then firefox runs into a same-origin policy error and you cannot access to window.location object

From MDN:

The same origin policy prevents a document or script loaded from one origin from getting or setting properties of a document from another origin. This policy dates all the way back to Netscape Navigator 2.0.
