title: Impossible to use a twitter timeline in firefox?
body: <p>When I try to use a twitter timeline, or view a twitter timeline on any site in Firefox I am greeted with the console warning:</p>
  
  <pre><code>The resource at "https://platform.twitter.com/widgets.js" was blocked because tracking protection is enabled.
  </code></pre>
  
  <p>I have three parts to this question:</p>
  
  <ol>
  <li><strong>Why is firefox blocking twitter timelines/widgets?</strong></li>
  <li><strong>What can I do to make the timeline show?</strong></li>
  </ol>
  
  <p>and the most infuriating:</p>
  
  <ol start="3">
  <li><strong>Why is this happening even though tracking protection is NOT enabled???</strong></li>
  </ol>
  
  <p>Here are some examples of timelines that get blocked:</p>

  <p>and last, but not least, proof that it is actually disabled:
