Firefox addon 以编程方式重新启动firefox扩展

我正在使用Mozilla插件sdk制作Firefox扩展。我在一个面板中显示一个特定的HTML页面。根据收到的特定事件，我希望重新加载扩展（而不仅仅是页面）。重新加载=重新运行main.js，就像浏览器重新启动时一样

仅重新加载HTML页面的问题在于，在重新加载时，页面工作程序仍然是旧的，并且在重新加载期间接收到的事件没有得到正确处理。与这些事件对应，您会得到以下错误：

Timestamp: 4/11/13 12:34:20 PM
Error: ubp-install: An exception occurred.
Traceback (most recent call last):
  File "resource://onebutton-at-user043-dot-com/addon-sdk/lib/sdk/panel.js", line 273, in _onHide
    this._emit('hide');
  File "resource://onebutton-at-user043-dot-com/addon-sdk/lib/sdk/deprecated/events.js", line 123, in _emit
    return this._emitOnObject.apply(this, args);

    listener.apply(targetObj, params);

  File "resource://onebutton-at-user043-dot-com/addon-sdk/lib/sdk/content/worker.js", line 404, in _emitEventToContent
    throw new Error(ERR_FROZEN);

简而言之，我需要一种重新加载firefox扩展的方法。

你能销毁页面工作程序并创建一个新的吗？
