This seems similar to Ghostery [1] for Firefox. It currently blocks 852 3rd part elements (371 advertising and 207 analytics) and 434 specific cookies. It also allows you to delete flash and silverlight cookies on exit.

I use Ghostery as well for both FF and chromium. For instance, it blocked 14 tracking scripts from that techcrunch article. I love it.

I always use the FF site so I was completely unaware they have an extension for Opera and IE as well as FF and Chrome.

Well, using ghostery, I just learned that there is such a thing called Microsoft Atlas (whatever that is).
