And for Nuke Overdrive mode, add a check for position: sticky, i.e.

  (function () {
    var elpos,i, elements = document.querySelectorAll('body *');
    for (i = 0; i < elements.length; i++) {
      elpos = getComputedStyle(elements[i]).position;
      if (elpos === 'fixed' || elpos === 'sticky') {
        elements[i].parentNode.removeChild(elements[i]);
      }
    }
  }
  )();
