关于firefox中i对象内DOM对象的获取
在firefox中i的属性可以采用.getElementById实现，但是DOM对象却不能通过此方式获得。中间很多人提到了跨域访问的问题。我个人觉得不应当是这个问题，而应当是属于对象获取的问题。
i对象当认为是一个DOM window窗口后，应.self.document对象可以获得内部的DOM结构。
示例文件：
1.status.xul
2.1.html
3.btn1.js
btn1.js
button1()
{
alert("button1 on ");
domain = "1.html";
title = contentview.title;
var name = contentview.name;
var window = contentview.self;
var doc = document;
title = "node ";
var btn2 = doc.getElementById("btn2");
var label = btn2.label;
btn2.label = "lalala";
btn2.text ="123";
btn2.name = "456";
btn2.innerHTML = "789";
}
