This test accesses the content page a bunch in this function:

function inspectPage(dropper, click = true) {
  let target = document.documentElement;
  let win = window;

  // get location of the content, offset from browser window
  let box = gBrowser.selectedBrowser.getBoundingClientRect();
  let x = box.left + 1;
  let y = box.top + 1;

  return dropperStarted(dropper).then(() => {
    EventUtils.synthesizeMouse(target, x, y, { type: "mousemove" }, win);

    return dropperLoaded(dropper).then(() => {
      EventUtils.synthesizeMouse(target, x + 10, y + 10,
        { type: "mousemove" }, win);

      if (click) {
        EventUtils.synthesizeMouse(target, x + 10, y + 10, {}, win);
      }
    });
  });
}

This is easily fixable (in fact it should have been fixed in bug 1246677, but I guess I missed it then).

This test has been rewritten in bug 1262437 and doesn't accesses CPOWs anymore. Plus, no failure reports since March. Closing.
