Free Anonymous Surfing

Anonymous surfing allows you to surf the web without leaving a trail of particulars about your browser, your computer system, your country, IP address, 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, and that site will retrieve the page for you and present it to you. The site you visit will not receive any particulars about your system, your IP address etc because the proxy will not have transmitted such particulars to it.
