Here's another useful one:

Proxify anonymous surfing: "A web-based anonymous proxy service which allows anyone to surf the Web privately and securely. The Proxify widget provides easy access to the Proxify service, directly from your Dashboard. Proxify hides your IP address and our encrypted connection prevents monitoring of your network traffic. Once using Proxify, you can surf normally and forget that it is there, protecting you."
