javascript - loadContextGoodies 未定义

Question

这是我非常简单的 Firefox 插件 main.js。我运行它并得到“loadContextGoodies 未定义”，这里出了什么问题？

const {Cc, Ci, Cu, Cr} = require("chrome");
var events = require("sdk/system/events");
var utils = require("sdk/window/utils");
var { MatchPattern } = require("sdk/util/match-pattern");
var pattern = new MatchPattern(/^https?:\/\/example\.com.*/);

function listener(event) {
    var channel = event.subject.QueryInterface(Ci.nsIHttpChannel);
    var url = event.subject.URI.spec;
    if (isToBeRedirected(url)) {
        channel.cancel(Cr.NS_BINDING_ABORTED);
            var goodies = loadContextGoodies(channel);
            var domWin = goodies.aDOMWindow;
            var gBrowser = goodies.gBrowser; 
            var browser = goodies.browser;
            var htmlWindow = goodies.contentWindow;
        browser.loadURI("about:blank");
    }
}

exports.main = function() {
    events.on("http-on-modify-request", listener);
}

function isToBeRedirected(url) {
    return pattern.test(url)
}

编辑:我完全忽略了用于重定向位的源代码部分，其中包含函数的声明。我没有注意到它是一个滚动框..不过还是谢谢你的回答。
