Dear Lifehacker, My favorite private BitTorrent tracker, Demonoid, has apparently gone down for good .
Firefox: It's not just Facebook that's actively tracking your movements on the Web without your consent: Google, LinkedIn, and others do the same, although most other services make it easier to opt out. If you want to use those services when you want without trading your privacy for the privilege, Priv3 is a Firefox extension that gives you back the ability to choose. Priv3 is the result of researchers at Rutgers University and the International Computer Science Institute (ICSI), an independent research center affiliated with the University of California at Berkeley. The extension doesn't completely block all third-party data transactions, but what it does is selectively stop social services like Facebook, Google (specifically Google's +1 button,) Twitter, and LinkedIn from dropping their tracking cookies on your computer and reading them when you're on other sites.
Over the weekend, Dave Winer wrote an article at Scripting.com explaining how Facebook keeps track of where you are on the web after logging in, without your consent. Nik Cubrilovic dug a little deeper , and discovered that Facebook can still track where you are, even if you log out. Facebook, for its part, has denied the claims .
It's no secret that there's big money to be made in violating your privacy. Companies will pay big bucks to learn more about you, and service providers on the web are eager to get their hands on as much information about you as possible. So what do you do?
