A truly powerful and uniquely capable addon that gives you unrestricted and direct control over your web browsing privacy. The interface and functionality aren't for the faint of heart, and you can easily end up giving yourself a hard time if you don't configure your rules correctly, but for the power user looking to take back control of their personal data on the web this is an invaluable tool with incredible potential. It gives you an inside look at just how many parties are snooping on your browsing habits, and the ability to thwart them directly. Highly recommended.
