Surfing the web anonymously

If you want to surf the web anonymously there is a simple solution - Proxy servers.
A proxy server is a server you can surf from using its identity and IP, there are sites that provide this server for free, here is a list of some of these sites:

http://www.youhide.com
http://youhide.net
http://anonym.to
http://www.allowu.com
http://www.avoidr.com
http://www.theproxyfree.com
http://www.proxybrowsing.com

All these proxy servers are pretty fast, but if they are uncomfortable, there is another way of using them - a firefox addon called SwitchProxy.
You can download it from here(this site has a guide on how to use the addon too): http://mozmonkey.com/switchproxy/
