while doing some research on anonymous surfing I came across different ways to achieve the same result, i.e. hide the IP address. Tor, Privoxy, Glype, Anonymizer, the Cloak, and many others seem to reach the goal in different ways. Although I can understand how the different solutions work in principle I would like to have a better understanding of the pros and cons of each approach, assuming that my objective is to browse Google and Yahoo in total anonymity (of course without using any account).
Can you please help me?
