1185985 - Twitter widgets and other Javascript constructs don't work in chrome nested iframes or browsers

Status: RESOLVED DUPLICATE of bug 1177795

(Firefox :: General, defect)

Description

[Mike Kaply [:mkaply]]

Given a XUL file that looks like this:

<?xml version="1.0"?>
<window xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
  <browser width="1000" height="1000" type="content" src="http://home.brandthunder.com/goduke"/>
</window>

On the resulting page, the Twitter widget doesn't load:

Error: Permission denied to access property "postMessage"

and clicking on the buttons doesn't work either:

Error: Permission denied to access property "location"

It appears that you can no longer nest a browser (or iframe) into a chrome XUL file and have it work properly (with or without e10s).

I've gone back to firefox 31 and this worked properly then.

I'll look into getting a regression window.

Is there some new way to put iframes and browsers into chrome URLs that I don't know about?

mozregression wasn't much help.

Huge window.

I bet it's

Need to look at the chrome manifest flags.

Neither of those chrome.manifest flags make this work.
