var cancelAnimationFrame = window.cancelAnimationFrame || window.mozCancelAnimationFrame;

var start = window.mozAnimationStartTime;  // Only supported in FF. Other browsers can use something like Date.now().

var myReq;

function step(timestamp) {
  var progress = timestamp - start;
  d.style.left = Math.min(progress / 10, 200) + 'px';
  if (progress < 2000) {
