页面滚动返回false在Firefox中不起作用

Question

我有一个可滚动的div，但是当用户在该div内滚动时，我希望页面的其余部分停止滚动。我能够使其在Chrome，Safari，Edge等中正常工作，但无法使页面停止在Firefox中滚动。我相信它与代码的“返回假”部分有关，但我不确定。我曾尝试将mousewheel更改为DOMMouseScroll，但这并不能解决问题。

有人对如何使它在Firefox中运行有任何想法吗？ IE 11也有问题。

下面是代码，这是一个Codepen-https://codepen.io/anon/pen/pYpqeJ

var scroller = {};
scroller.e = document.getElementById("scroll");

if (scroller.e.addEventListener) {
  scroller.e.addEventListener("mousewheel", MouseWheelHandler, false);
  scroller.e.addEventListener("DOMMouseScroll", MouseWheelHandler, false);
} else scroller.e.attachEvent("onmousewheel", MouseWheelHandler);

function MouseWheelHandler(e) {
  // cross-browser wheel delta
  var e = window.event || e;
  var delta = -30 * Math.max(-1, Math.min(1, e.wheelDelta || -e.detail));

  var pst = $("#scroll").scrollLeft() + delta;

  if (pst < 0) {
    pst = 0;
  } else if (pst > $(".box-wrap").width()) {
    pst = $(".box-wrap").width();
  }

  $("#scroll").scrollLeft(pst);

  return false;
}

$("#scroll").off("mousewheel").on("mousewheel", function(ev) {
  var el = $(ev.currentTarget);
  return ev.originalEvent.deltaY > 0
    ? el[0].scrollWidth - el.scrollLeft() <= el.innerWidth()
    : el.scrollLeft() === 0;
});

$(window).scroll(function() {
  buffer = 100 // # of pixels from bottom of scroll to fire your function. Can be 0
  if ($("#scroll").prop('scrollWidth') - $("#scroll").scrollLeft() <= $("#scroll").width() + buffer )   {
document.getElementById("scroll").style["background"] = "pink";
    return false;
    event.preventDefault();
    $('#scroll').css('overflow', 'scroll');


  }
});

#wrap {
  max-width: 600px;
  margin: 0 auto;
}

#scroll {
    width: 600px;
    border: 1px solid #111;
    padding: 0px;
    margin: 0px;
    overflow-x: scroll;
    overflow-y: hidden;
}

.box-wrap{
    padding: 0px;
    margin: 0px;
    height: 200px;
    width: 2040px;
}

.box {
    height: 200px;
    width: 200px;
    padding: 0px;
    background: #123;
    display: inline-block;
    color: #fff;
    font-size: 20px;
    text-align: center;
    line-height: 200px;
}
