Do-Not-Track developments

Several interesting developments in the world of Do-Not-Track this Monday:

Firefox Do-Not-Track header

The Firefox implementation of Do-Not-Track landed in a nightly build. PC World, among others, reported on it. The relevant bugzilla bugs for discussion and code review are:

• Bug 628197: Implement Do-Not-Track HTTP header
• Bug 628198: Implement UI for do-not-track HTTP header

CDT draft Do-Not-Track definition

Also, the Center for Democracy and Technology (CDT) released a draft definition of "Do Not Track." This document sets out a taxonomy of data collection techniques and categorizes some as "tracking", excluding others. Note that the actual document is a PDF linked from the top of the blog post - it took me a moment to find it.
