User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 Build ID: 20160105164030 Steps to reproduce: 1. page at domain1 contains iframe with src="domain2". there is no relation between the domains. 2. page in the iframe creates EventSource object to an URL in domain2 (same domain as the web page loaded to the iframe) Actual results: 1. EventSource object reports error: Firefox is unable to connect server "domain2" 2. Console shows url of the request as XHR XMLHttpRequest works in this situation and can be used as workaround. This example will work well also in Chrome. Expected results: 1. EventSource object should not report error because it is no XHR request
Dan, can you take a look at this bug?
Works for me: I took a page on a test domain and added an iframe to http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_sse ... and the EventSource example in that page continued to work. I tested in both Nightly (49) and ESR-38.8 Without a testcase showing the problem there's not much we can do here.
