I got an iframe of different domain than mine and I got firefox security a little down by setting tis stuff to "allAccess".

Now I can do frame.contentDocument.createElement("div"); all without any error (not even the permision denied) I can set the innerHTML all fine and dandy. The problem is when I use frame.contentDocument.body.appendChild. I resolved the permision denied issue by enabling firefox policies to allAccess but now I get this error:

[Exception... "Node cannot be inserted at the specified point in the hierarchy" code: "3" nsresult: "0x80530003 (NS_ERROR_DOM_HIERARCHY_REQUEST_ERR


I want to append a div to the body of an iframe who's on a different domain. This is firefox specific and I don't care with compatibility. How can I resolve that issue?

If I can execute javascript within the iframe that would be great. I have no control of coding of the site the iframe display's

Thank you
