【问题描述】：
我正在绝望地寻找一种方法来在它打开时填写撰写消息，在一个 boostraped（无重启）TB 附加组件中。
这是我在我的非引导加载项 RemindIt 中所做的事情
感谢Superjos，我能够管理不同的侦听器，并在打开时让撰写消息充满我的自定义消息。
但是...这仅适用于新的（非回收的）窗口。如果我关闭一个撰写窗口，然后单击“新消息”，它会被回收（我猜）并且不会触发“加载”事件。
我尝试了不同的技巧（例如参见 onComposeInit2），但最后，我无法更改非新窗口的撰写消息，即使看起来我的插件正在调用编辑方法（这是可以在日志中看到）。
有什么想法吗？
查看我的 test/bootstrap.js 代码：
function log(s){
Components.classes["@mozilla.org/consoleservice;1"]
.getService(Components.interfaces.nsIConsoleService).logStringMessage("test: "+s);
}
