HttpFox breaks notificationCallbacks

[Jeferson Hultmann]

Hi Martin and all,

The following snippet throws an exception when HttpFox is active
(via start button).

// http-on-examine-response
observe: function(aSubject, aTopic, aData) {
var w = aSubject
.QueryInterface(Ci.nsIHttpChannel)
.notificationCallbacks
.getInterface(Ci.nsIWebProgress);
}

[Exception... "Component returned failure code: 0x80004005
(NS_ERROR_FAILURE) [nsIInterfaceRequestor.getInterface]"
nsresult: "0x80004005 (NS_ERROR_FAILURE)"

or

[Exception... "'Component does not have requested interface'
when calling method: [nsIInterfaceRequestor::getInterface]"
nsresult: "0x80004002 (NS_NOINTERFACE)"

I think it happens because HttpFoxRequestEventSink.init
overrides notificationCallbacks...
