Targeted Advertising Cookie Opt-Out

Targeted Advertising Cookie Opt-Out is a Firefox add-on that has gained popularity amongst users for its ability to block targeted advertising by 27 different advertising networks. These networks include heavyweights such as Google/Doubleclick and several members of the Network Advertising Initiative.

The highlight feature of this add-on is that it sets permanent opt-out cookies in the browser of the user, which prevents any information collection by the 27 different online advertising networks. These are generic and non-personally identifiable opt-out cookies, ensuring that user privacy is not compromised.

Unlike its predecessors, this add-on ensures complete persistence of cookies, even after the user clears all other installed cookies from their preferences. It is important to note that deleting the add-on is a requirement for users wanting to remove the 41 cookies installed, some of which are needed for different domain names.

The simple solution to see this add-on in action is to delete all installed cookies from the preferences window. Compatibility with multiple platforms such as Mac OS X, Windows, and Linux ensures that a wider user base can benefit from the features of Targeted Advertising Cookie Opt-Out.
