do not track
Third-party browser tracking -- and how to give users more control over it -- is a hot topic right now. Microsoft and the FCC have similar plans, one former Google employee recently took the wraps off his take, and now there's another Chrome extension which turns the tracking blocker knob up to eleven.
Do Not Track (DNT) ChromeBlock, and it gives you an easy way to shut down around 90 different Web tracking networks. Just about every well-known harvester is listed: Google, MSN, Alexa, Doubleclick, Omniture, Quantcast, Tynt and Cleeki, to name a few. You can choose to block networks as DNT detects their presence on a page, or you can opt out in advance by clicking the show global settings link. The overlay on DNT's browser action button tells you how many networks are detected and how many you've chosen to block.
Do Not Track works nicely in tandem with Disconnect, so those of you looking for as much tracking protection as possible can go ahead and install both extensions. Even if you're not concerned with blocking the connections, it's very interesting to see which sites you browse are sending data to different providers.
