Modify Headers 0.6.6

编辑头HTTP文件,可以添加修改HOST,USER-AGENT等信息.

https://addons.mozilla.org/firefox/967/
Add, modify and filter http request headers. You can modify the user agent string, add headers to spoof a mobile request (e.g. x-up-calling-line-id) and much more. Take a look at the help tab of the Modify Headers window.

Some people think that ‘user-agent’ is a custom way of specifying the user agent string. This is not true, for a guide on this and other HTTP request headers, look at the W3C guide: http://www.w3.org/Protocols/HTTP/HTRQ_Headers.html
