Privoxy is a standalone application full of impressive features. It’s a breeze to install. Its default settings are ideal for most users. Fedora and Ubuntu users can respectively install it with the commands
yum install privoxy and
sudo apt-get install privoxy, or you can grab the source tarball and install it with the commands
./configure, make, make install. Once installed, Privoxy will bind to localhost (127.0.0.1) at port 8118. You can choose a different port and network interface during the manual installation, or specify it under section 4.1 of the /etc/privoxy/config file.
