非标准
该特性是非标准的，请尽量不要在生产环境中使用它！
返回chorme浏览器窗口下的XUL控制器。
controllers = window.controllers
controllers 是 XULControllers (nsIControllers)类型的一个对象.XUL-专用， 不属于任何规范。
默认情况下，窗口的控制器包含支持全局窗口命令的代码。
Chrome代码可以添加控制器（与globalOverlay.js中的goDoCommand和goUpdateCommand函数配合使用）。
然而，当浏览器窗口关闭时候，这些添加的控制器我们必须手动删除，因为浏览器并不会自动的完成这些操作。
每当有忘记删除的控制器都会引起错误：
