以编程方式重新启动Firefox扩展

Question

我使用Mozilla addons-sdk制作Firefox扩展程序。我在面板中显示特定的HTML页面。基于收到的某个事件，我想重新加载扩展（而不仅仅是页面）。重新加载=重新运行main.js，就像浏览器重启时一样。

重新加载HTML页面的问题在于，当重新加载发生时，页面工作者仍然是旧的，并且在重新加载期间收到的事件未得到正确处理。对应于这些事件，您会收到以下错误：

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);
  File "resource://onebutton-at-user043-dot-com/addon-sdk/lib/sdk/deprecated/events.js", line 153, in _emitOnObject
    listener.apply(targetObj, params);

    emit: function () self._emitEventToContent(Array.slice(arguments))
  File "resource://onebutton-at-user043-dot-com/addon-sdk/lib/sdk/content/worker.js", line 404, in _emitEventToContent
    throw new Error(ERR_FROZEN);
Error: The page is currently hidden and can no longer be used until it is visible again.

简而言之，我需要一种方法来重新加载firefox扩展。
