给Firefox加入一个Dict的词典按钮

其实很简单，首先：菜单“查看/Add New Button”建一个新按钮，如下添入
1、先装这个插件
2、代码如下
/*Code*/
var  element=content.document.createElement('script');
element.setAttribute('src', 'http://dict.cn/hc/init.php');
content.document.body.appendChild(element);
3、图片如下

4、名称当然自己起，就叫Dict吧

建好之后的按钮在 “定制工具栏里” 睡觉。在导航栏右击鼠标，选择定制就找到了。
再吗，就是把蓝色的“D”拖到要放的工具栏上就OK了。
用的时候，要当前页面javascript可用，然后点击这个按钮，再然后就可以划记搜索，查询英语单词了
