nBlock

A network-wide web content filtering & blocking eCAP adapter for Squid.
nBlock Aims to replace all sorts of privacy enhancing browser plugins like AdBlock Plus, Decentraleyes, Self-Destructing Cookies and fills the content filtering gaps that come with DNS only filters like Pi-Hole.

Please read the installation instructions on how to set up your own instance of nBlock.
