+<h3>Do Not Track</h3>
+
+<p>A few years ago the W3C (World Wide Web Consortium) created a mechanism for browsers to inform web servers that they would not like to be tracked.
+ This is accomplished by including a <a href="https://en.wikipedia.org/wiki/Do_Not_Track">DNT (Do Not Track) header</a> with web requests.
+ This header is enabled by default in Privacy Browser, although if desired it can be disabled in the settings.</p>
+
+<p>The DNT header doesn't really provide much privacy because most web servers ignore it. Yahoo programmed their servers to ignore the DNT header
+ from Internet Explorer 10 when it was turned on by default because they argued that the user had not made the decision to enable DNT.
+ Google and Microsoft ignore DNT even though they include a DNT feature in the browsers they distribute. Facebook also ignores DNT.</p>

<p>Verizon, one of the major mobile carriers in the United States, adds a unique tracking header to all HTTP traffic on their network. The Electronic Frontier
Foundation has written about the <a href="https://www.eff.org/deeplinks/2014/11/verizon-x-uidh">privacy implications of this practice</a>. Due to public pressure
Verizon has created a way to <a href="http://www.clark.com/how-opt-out-verizons-super-cookie-tracking">opt out of this tracking</a>.</p>
