If you want surf anonymous use tor from eff. From the tor Web site:
Tor: An anonymous Internet communication system
Tor is a toolset for a wide range of organizations and people that want to improve their safety and security on the Internet. Using Tor can help you anonymizing web browsing and publishing, instant messaging, IRC, SSH, and other applications that use the TCP protocol. Tor also provides a platform on which software developers can build new applications with built-in anonymity, safety, and privacy features.

Another anonymizer is JAP, which can be found here: http://anon.inf.tu-dresden.de/. It works more or less like Tor, except JAP just support HTTP, HTTPS and FTP as protocol. JAP encrypts our web traffic (RSA1024 and AES128) and sends it to a (mix) proxy. At the moment there aren’t a lot of public proxies available.. and without mixing the proxies its (theoretical) not that anonymous. But you can use JAP as Tor Client (instead of installing Tor, TorCP and Privoxy). To use JAP as Tor Client change the proxy type in your Browser from HTTP to SOCKS!
JAP is working fine with CookieCooker. This Tool shares your cookie with other CookieCooker Users so if someone will trace you, he will get unusable results, as the cookies are shared.
For example, if you want to download a file but you need to register, you can use CookieCooker, perhaps someone already created a user for this website. You can also mark a web site as trusted, so you don’t share this cookie. Unfortunately CookieCooker is not free, after 7 days they want 15 Euro.
A quick and dirty Tor/Provoxy How-To:
Setup and install Tor
Install Tor, TorCP (Tor Control Panel) and Privoxy. The easiest way is to download the bundle (all 3 tools, 1 installer).
If you installed those 3 tool manually you need to configure Privoxy (Skip this step if you installed the bundle):
You need to configure Privoxy to use Tor. Open Privoxy’s “config” file (Option / Edit Main Configuration) and add the line
“forward-socks4a / localhost:9050 .”
to the top of the config file. Don’t forget to add the dot at the end.
Using privoxy is necessary because browsers leak your DNS requests when they use a SOCKS proxy directly, which is bad for your anonymity. Privoxy also removes certain dangerous headers from your web requests, and blocks obnoxious ad sites like Double click.
Dataflow for web browser:
When you want to use Socks capable applications (Gaim, ICQ…) you can directly connect to Tor:
[socks application]–[Tor]–(virtual tunnels)–[destination]
Now we need to setup your browser.. But first check you IP, for example go to http://ipid.shat.net/. Now enable Proxy Server for your Web Browser (set it to 127.0.0.1, Port 8118) and go to http://ipid.shat.net/ again. The IP should be different now.
