"EFF is launching a new extension for Firefox and Chrome called Privacy Badger. Privacy Badger automatically detects and blocks spying ads around the Web, and the invisible trackers that feed information to them."
From the launch description:
Privacy Badger is EFF's answer to intrusive and objectionable practices in the online advertising industry, and many advertisers' outright refusal to meaningfully honor Do Not Track requests. This week, Mozilla published research showing that privacy is the single most important thing that users want from their web browsers. Privacy Badger is part of EFF's growing campaign to deliver that privacy by giving you the technical means to disallow trackers within the pages you read on the Web.
This is an alpha release; we've been using it internally and don't think it's too buggy. But we're looking for intrepid users to try it out and let us know before we encourage millions of people to install it. If you find bugs, you can file them on github against either the Firefox or Chrome repos as appropriate.

from what I understand, its a heuristic version of Disconnect/Ghostery without a pre-defined blacklist that only blocks things on your browser that attempt to track you across pages (such as static image trackers and so on), it seems rather interesting but given its early development state I opted to hold off on testing it for a while until things settle down.
I like the idea of it.

So if I block third-party cookies then this extension is moot?

Probably not.
Allow me to speculate on how this new tool might work: look for sites that provide 1px images and are included via plain old HTML (JavaScript optional).
If such hosts are referenced on > 1 site, heuristics indicate that they ought to be blocked.
Cookies wouldn't come into play in this scenario, yet such a tool could still block some significant amount of tracking.

Aha, very clever. So in theory Adblock Plus's EasyPrivacy list should block the tracking site, but this new tool will catch tracking sites that the filter list has missed. And being plain-HTML based, noscript/disconnect/taco will all miss it.
