+ <h3><svg class="header"><use href="../shared_images/location_off.svg#icon"/></svg> 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.</p>
+
+ <p>The DNT header doesn't really provide any privacy because most web servers ignore it. For example, Yahoo, Google, Microsoft, and Facebook all ignore at least some DNT headers.
+ Beginning with version 3.8, Privacy Browser no longer has the option to send a DNT header.</p>
+
+
+ <h3><svg class="header"><use href="../shared_images/link_off.svg#icon"/></svg> URL Modification</h3>
+
+ <p>Privacy Browser removes tracking IDs and AMP (<a href="https://en.wikipedia.org/wiki/Accelerated_Mobile_Pages">Accelerated Mobile Pages</a>) redirects from URL queries.
+ There is a blog post that is updated with the <a href="https://www.stoutner.com/url-modification/">current list</a> of modifications.
+ URL modification can be turned off in the settings if it is causing issues.</p>
+
+
+ <h3><svg class="header"><use href="../shared_images/disabled_by_default.svg#icon"/></svg> X-Requested-With Header</h3>
+
+ <p>Google programmed Android’s WebView to send an <a href="https://www.stoutner.com/the-x-requested-with-header/">X-Requested-With header</a> with every request.
+ The value of the X-Requested-With header is set to the application ID, which in the case of Privacy Browser is <code>com.stoutner.privacybrowser.standard</code>.
+ This can be disabled using <a href="https://www.stoutner.com/webview-devtools/">WebView's DevTools</a>.</p>
