Free Anonymous Surfing, Free Proxies

Anonymous surfing allows you to surf the web without leaving a trail of particulars about your browser, your computer system, your country, IP address, list of fonts installed on your computer (yes, websites can find that out from your browser too, if they want to), etc. This is usually done by entering the address (URL) of the site you wish to go to at the free anonymous surfing proxy site. The latter will then retrieve the page and present it to you. The site you visit will not receive any particulars about your system or your IP address because the proxy will not have transmitted such particulars to it.
If you are particularly concerned about privacy and anonymity while surfing, you should note that, when using most of the free anonymous surfing facilities, the URLs you visit and the content of those pages are easily gleaned by others. If absolute privacy is your concern, you might want to explore commercial solutions such as Steganos Internet Anonym and Anonymizer's Total Net Shield which encrypt all your traffic (including your URLs) in a Virtual Private Network (VPN) giving you privacy from people snooping your connection (say) when you're connected via wireless broadband, and even privacy from your ISP. Some of these commercial solutions may provide other benefits as well, such as encrypting your email, internet messaging (IM) and chats, etc.
