New Firefox Feature Blocks Behavioral Ads

[Jack]

The feature will allow users to configure their Firefox browser to tell websites and advertisers that they would like to opt-out of any advertising based on their behavior, Alex Fowler [cq] wrote in his blog post. The user’s preference is communicated to websites and third party ad servers using a new “Do Not Track HTTP header”, which is sent with every click or page view in Firefox.

It is a nice feature to have. On the other hand many free products and online services exist only because of the advertising (google, facebook, etc.). Also sites might choose not to respect the Do Not Track HTTP header.
