Emerge
To install Privoxy:
root #emerge --ask net-proxy/privoxyBoot service
OpenRC
To start privoxy:
root #/etc/init.d/privoxy startTo make privoxy start at boot:
root #rc-update add privoxy defaultConfiguration
Browsers need to set the proxy configuration to address 127.0.0.1 and port 8118 in the browser proxy configuration or in a proxy plugin (like foxyproxy). Privoxy default configuration block ads and further configuration should edit files in /etc/privoxy/.
Test filters
There is a way to test the filters that are applied to a specific site.
If privoxy is working correctly the next URL should be intercepted by privoxy
http://config.privoxy.org/show-url-info
In this page it's possible to check why a page is filtered or what filters are applied to that site.
