That's the "Same Origin Policy" in action -- IE8 is more lax than FireFox, and will allow calls to a different port in the same website. With Firefox, if you load the program from http://www.yoursite.com:8080, then you cannot do any RequestBuilder calls to any other URL; IE8 allows changing the port, so you can call http://www.yoursite.com:8889
