title: Firefox image selection color
body: <p>I changed the selection color of the text with this CSS: 
  </p>
  
  <pre><code>::-moz-selection {
      background: #D9230F;
      color: #FFFFFF;
  }
  ::selection {
      background: #D9230F;
      color: #FFFFFF;
  }
  </code></pre>
  
  <p>But the image selection color in Firefox is still blue. How can I change that?</p>

  <p><strong>EDIT:</strong> I want the image to be <em>selectable</em>, so <code>user-select: none</code> doesn't help me.</p>
