This site offers a free do not track me add on that will block over 600 different tracking agencies. The addon apperas to be free but I believe you can pay more and get a better service.

This link is for Firefox users and is absolutely free.

Both will block most tracking companies.

If you're ever worried about new ones popping up in the future, simply run the index.dat viewer again and see if anything strange pops up.

It only takes a few minutes to do all of this.

Well worth it in my opinion.
