Privaxy

Next generation tracker and advertisement blocker. 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.
