Does the "Do-not-track" feature of Firefox 5 involve the use of cookies? In other words, will the web sites which decide to honor the "Do-not-track" push a cookie to Firefox which indicates my preference, for every time I visit that web site? I am asking this question because I use cookie management. For most web sites I set cookies to "Allow for session" but when I see a cookie named "Tracking" or "Metrics" I set those cookies to "Deny." Therefore, I'm wondering if my cookie management is defeating the intended function of the "Do-not-track" feature as envisioned by Mozilla. I mean, in layman's terms how is "Do-not-track" supposed to work? How can I tell if it's working? If this has already been explained elsewhere please direct me to that article/document. Thank you.
