Modify Headers by Gareth Hunt

Add, Replace and Filter HTTP request headers. Modify Headers allows modification of the HTTP request headers sent to web servers. This addon is particularly useful for Mobile web development, HTTP testing and privacy.

For a guide on HTTP request headers, look at this W3C page: http://www.w3.org/Protocols/HTTP/HTRQ_Headers.html
