(Whiteboard: [pdfjs-integration]) 

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170323105023

Steps to reproduce:

HTML
------
<!doctype html><html><head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<script src="http://www.example.com/path/y.js"></script>
</head><body onload="get_iframe()">
<iframe id="doc_frame" src="http://www.example.com/path/file.pdf"></iframe>
</body></html>

JAVASCRIPT FILE (y.js)
-------------------------
function get_iframe () {
    console.log(document.getElementById('doc_frame').contentWindow.document);
}



Actual results:

When trying to get the iframe document (from within the .js file), I get this permission error:

Error: Permission denied to access property "document"


Expected results:

I should be able to get the document.  All paths are identical (location of html file itself, src in iframe and js file).

This only happens in ff.

Hi, I experience the same issue, is there any known workaround?

The error is now Uncaught DOMException: Permission denied to access property "document" on cross-origin object.
