Firefox addon SDK replace request

I tried to replace by a local script the url of scripts loaded by websites.

I tried to channel.redirectTo with data.url and chrome, but doesn't work, so I compared a regex pattern, if true, it will cancel the XHR GET request.

For example

<script src="url/to/script.js"></script>

become

<script src="resource://url/to/new/script.js"></script>

or

<script src="chrome://url/to/new/script.js"></script>

Now I need to replace the url or inject my new script to the page

main.js

var listener = function (event) {
    var channel = event.subject.QueryInterface(Ci.nsIHttpChannel);
    var match = someFunctionToMatchRegex(channel.URI.spec);
    if (match) {
        channel.cancel(Cr.NS_BINDING_ABORTED);
    }
};

events.on("http-on-modify-request", listener);
