Ghostery

I've been using Ghostery for quite awhile & it is my #1 blocker.

The UI is extremely intuitive. Access to more info on every site it filters is an invaluable resource for me. It is very easy to add / remove blocking, which is helpful to see what blocks might be preventing a website's functionality.

I highly recommend!

Very easy to use and a great concept. Why should we not be able to choose our own privacy levels and what we are exposed to online?

A useful Firefox add-on, this examines every page you visit and reports on the invisible trackers, bugs and beacons that may be being used to monitor your activities. These are normally associated with ad distributors, and Google, though it isn't that hard for anyone to follow you around without your knowing, if they have the skills to implement the code.

There is an option to view a caption which overlays a small area of the page, listing all the services discovered, or to have a link in your toolbar or both. A very nice touch is the capability to then visit the Ghostery reference page which describes known information about that service.

You also have the opportunity to block any of these services, if you don' t already have other blocking add-ons doing that for you.

It's a revealing and helpful add-on that doesn't seem to have any negative aspects at all. Recommended, along with Ad-block Plus, Flashblock and NoScript as basic security measures.
