Use Fiddler with Firefox

Fiddler is a awesome tool for monitoring the net traffic and it is free for download. Yeah, I knew that there is a FireBug, which also can help you monitor the net traffic. Why bother?

The FireBug console is a plug-in to the Firefox browser, and it is window based, which I guess each tab will have a different FireBug instances for monitoring the HTTP traffic. So there is no central place for monitoring HTTP traffic from all opened browser windows. If something goes wrong in the window, which is then closed, the record for the HTTP traffic before the error occurs will be missing. By letting the Fiddler monitor the HTTP traffic in your Firfox browser will avoid this issue.

Fidder works very well with IE browser and no effort will be required to let Fiddler monitors the HTTP traffic in the IE browser. For Firefox, you need to

* Open options from the Tool menu item and click Advanced tab
* Go to Network | Connection Settings
* Use the Manual proxy configuration option
* Set Http proxy to 127.0.0.1 and Port 8888
