Analyzing the tracking services on any given website, Privacy Badger is a new plugin by the Electronic Frontier Foundation to guard against spying of your activity online.
Leo says it works great, but it raises an ethical question. Websites, especially those with ads, are free, and Privacy Badger effectively takes the money out of their pockets. It's like giving you a magazine with all of the ads cut out of it. Leo says in spite of the ethical dilemma, it's a good idea. And it makes your online surfing a lot faster.
