FoxNews is behind the times.
A Do-Not-Track button is already available as an add-on for Firefox and IE.
Check it out at: http://abine.com/
BUT, please do check out the Ghostery and Trackerblock add-on links in the article. Both are great additions to the Do-Not-Track option. Both give you a look at what the real scope of what has been added to your browser PRE and POST use of a DNT option.
I am running Firefox 3.6. 2 questions: should I upgrade to the new firefox browser? How do I delete all tracking cookies? As you can see I am not computer savvey so any help would be appreciated
