title: "This site appears to use a scroll-linked positioning effect. This may not work well with asynchronous panning"
body: <p>I have been given this unusual warning from Firefox. The positioning effect it refers to is a <code>div</code> I rotate as a factor of the scroll height. I have never had any problems with it, but is this something I should be concerned about? Is there anyway to have such effects without this warning?
  The JavaScript that demonstrates this issue is:</p>
  <pre><code>$('.gear').css({
     'transition': 'transform 1s ease-out',
     '-webkit-transform': 'rotate(' + Math.round(wScroll / 2) + 'deg)',
     '-moz-transform': 'rotate(' + Math.round(wScroll / 2) + 'deg)',
     '-ms-transform': 'rotate(' + Math.round(wScroll / 2) + 'deg)',
     'transform': 'rotate(' + Math.round(wScroll / 2) + 'deg)',
  });
  </code></pre>
  <ul>
  <li><code>wScroll</code> is the current scroll height</li>
  </ul>
