Debian tor + privoxy

$ cat /usr/share/doc/tor/README.privoxy
Tor only provides TCP layer anonymity.  It does not do any protocol
cleaning, so if you are going to browse the web you still give away a
lot of information to servers.

The privoxy package provides a privacy enhancing HTTP proxy, which
is good at filtering headers, cookies, and much more.  To view the
description of the Debian privoxy package just run "apt-cache show
privoxy".  Please refer to the privoxy documentation for more details.

In order to use privoxy over tor, add the following line to your
privoxy configuration file:
        forward-socks4a / localhost:9050 .
(the dot is important)

Then configure your browser to use privoxy as its HTTP proxy.
