+      <h4>The video controls are not showing up?</h4>
+      <p>This extension is only compatible with HTML5 video. If you don't see the controls showing up, chances are you are viewing a Flash video. If you want to confirm, try right-clicking on the video and inspect the menu: if it mentions flash, then that's the issue. That said, <b>most sites will fallback to HTML5</b> if they detect that Flash it not available. You can try manually disabling Flash plugin in Chrome:</p>

+        <li>In a new tab, navigate to <code>chrome://plugins</code></li>
+        <li>Disable "Adobe Flash Player"</li>
+        <li>Restart your browser and try playing your video again</li>
