Part of my code won't work in Firefox

Question

I'm not really good at coding and I have some problems with my code. I create animated menu in Edge Animate using jquery and then imported it in Muse as a edge file. It's working perfect in IE and Chrome, but something caused problems in Firefox - menu start animation just don't work in Firefox when scroll down. I appreciate any help!
Label = "begin";
sym.$("menuover").hide();
var h = $(window.parent).height()

var element10 = sym.getSymbol("projectbut").$("title");
var element15 = sym.getSymbol("beginbut").$("title");
fired10 = true;
var fired11 = true;
$(window.parent).on('scroll', function b1() {
var $this = $(this),
  $head = $('#head');
   if ($this.scrollTop() > h && Label == "begin" && fired11 === true) {
  fired10 = false;
  fired11 = false;
var element3 = sym.$("menuback");

Thanks Király, the System Profiler was exactly what I needed. Some of my Apps didn't show up in Roaring Apps so the PowerPC indicated against the non-compatible apps in System Profiler was very useful.
