我正在为 Firefox 创建一个简单的引导加载项。我需要通过单击按钮通过侧边栏从浏览器中捕获当前 URL。
我的bootstrap.js:
const {classes: Cc, interfaces: Ci, utils: Cu} = Components;
Cu.import('resource://gre/modules/Services.jsm');
Cu.import("resource://gre/modules/NetUtil.jsm");
Cu.import("resource://gre/modules/FileUtils.jsm");

.getInterface(Ci.nsIDOMWindowInternal||Ci.nsIDOMWindow);
aDOMWindow.addEventListener("load", function () {
aDOMWindow.removeEventListener("load", arguments.callee, false);
windowListener.loadIntoWindow(aDOMWindow, aXULWindow);

我尝试了从 Firefox 侧边栏扩展获取当前页面 URL 中的所有建议,但没有任何效果。
