Brief: 

1.Fiddler的运行机制其实就是本机上监听8888端口的HTTP代理。 Fiddler2启动的时候默认IE的代理设为了127.0.0.1:8888，Chrome的代理也是默认设置的。而其他浏览器是需要手动设置的，所以将Firefox的代理改为127.0.0.1:8888就可以监听数据了

(1) IE的proxy setting:

IE tools->Internet Options->"Connections" tab-> "LAN settings" button->"Proxy Server", "Advanced" button->Proxy settings.

(2) Firefox的proxy setting:

Tools -> Options->"Advanced" tab - > "Network" tab -> Connections, "Settings" button->"Manual proxy configuration" audio.

 

(3) Chrome的proxy setting:

点击Settings -> Show advanced settings... ->Network, “Change proxy settings...” - > "Connection" tab, "LAN settings" button->Proxy Server, select "Use a proxy server for your LAN" checkbox,  Click "Advanced" button.

IE和Chrome的设置窗口是一样的，Why？？

2. 修改Firefox 中的代理比较麻烦， 不用fiddler的时候还要去掉代理。推荐你在firefox中使用fiddler hook 插件. 当你安装fiddler后， 就已经装好了Fiddler hook插件， 你需要到firefox中去启用这个插件:
(1) firefox tools->Add ons -> Extensions -> Enable "FiddlerHook"

(2) firefox tools-> Monitor with Fiddler->use Fiddler automatically.
