标题: 将 JSON 对象通知出去
var jsonObj = {};
var observerService = Components.classes["@mozilla.org/observer-service;1"]
            .getService(Components.interfaces.nsIObserverService);

jsonObj.wrappedJSObject = jsonObj;
observerService.notifyObservers(jsonObj, "JsonObjNotify", "");

接收时：
observerService.addObserver(observer, "JsonObjNotify", false);
observe: function(subject, topic, data) {
      var jsonReceived = subject.wrappedJSObject;
}

即可。详情请见：https://developer.mozilla.org/en-US/docs/wrappedJSObject
