Hi Kyle, Thanks for this. I need to replace the XMLHttpRequest constructor with my own constructor, so I can't call createSystemXHR directly. I'll see if I can figure out from the code how to do this. Currently I have to admit that I don't understand how the code addresses the issue of giving content access to the responseXML DOM returned by the Cc['@mozilla.org/xmlextras/xmlhttprequest;1']. To reiterate my problem: I am replacing the default implementation of XMLHttpRequest with my own wrapper than delegates to Cc['@mozilla.org/xmlextras/xmlhttprequest;1']. Everything works fine except that the DOM returned by the responseXML property returns an error (Permission denied to access property 'documentElement') when I try to retrieve its properties. Clearly there is a wrapper in play but exactly what kind of wrapper and how to penetrate it is not yet clear to me. I guess the reason I'm suddenly having this problem is https://bugzilla.mozilla.org/show_bug.cgi?id=809652 but I can't be sure since I don't have access to it. _______________________________________________ dev-platform mailing list [email protected] https://lists.mozilla.org/listinfo/dev-platform
