Google’s “Do Not Track” Button Now Available
http://www.engadget.com/2012/02/24/google-tests-the-do-not-track-waters-with-a-chrome-extension/
If you are concerned with Google’s “do not evil” not being quite the mantra it once was, there is an option for Chrome that will allow you to opt out of your online activity tracking. It has actually been out for quite some time. With Chrome, review the article then, if interested, click on the link near the bottom of the body text to bring up that add-on and install it.
It didn’t work for me????
Inside of Chrome, click on the little wrench symbol near the upper right-hand side, then Tools > Extensions. Search for Keep My Opt-Outs then add the add-in to your list of Chrome add-ins.
