firefox 模拟手机

不想增加User Agent Switcher扩展，还是从Firefox本身下手。

1. about:config
2. 新建字符串
   

   general.useragent.override

3. 输入值
   

   Opera/12.02 (Android 4.1; Linux; Opera Mobi/ADR-1111101157; U; en-US) Presto/2.9.201 Version/12.02

其他浏览器的User Agent String可以参见User Agent String.Com的List of User Agent Strings：
http://www.useragentstring.com/pages/useragentstring.php
基本包含了国外各种软硬件浏览器的UserAgent。

Chrome for Android的User-Agent参考官方的：
https://developers.google.com/chrome/mobile/docs/user-agent
