#Privaxy is a #MITM HTTP(s) #proxy that sits in between HTTP(s) talking applications, such as a web #browser and HTTP servers, such as those serving websites.

By establishing a two-way tunnel between both ends, Privaxy is able to block network requests based on URL patterns and to inject scripts as well as styles into HTML documents.

Operating at a lower level, Privaxy is both more efficient as well as more streamlined than browser add-on-based blockers. A single instance of Privaxy on a small virtual machine, server or even, on the same computer as the traffic is originating from, can filter thousands of requests per second while requiring a very small amount of memory.

Privaxy is not limited by the browser’s APIs and can operate with any HTTP traffic, not only the traffic flowing from web browsers.

Privaxy is also way more capable than DNS-based blockers as it is able to operate directly on URLs and to inject resources into web pages.
