740576 - window.postMessage does not match on targetOrigin if page is loaded from file system as "file://"

Status: RESOLVED DUPLICATE of bug 431935

(Firefox :: Untriaged, defect)

Description

[brian]

Attachment: simple html file with the test case

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:11.0) Gecko/20100101 Firefox/11.0
Build ID: 20120310010316

Steps to reproduce:

Run the following script in a page that is loaded from the file system:

	window.postMessage('message with location', window.location);
	window.postMessage('message without location', '*');

	window.addEventListener('message', function(event) {
		console.log('message received: ' + event.data);
	});


Actual results:

Both messages should be received, but only the message without a targetOrigin is received. The restricted message is ignored completely.

The script works fine and both messages are received if the file is loaded from a web server.
