Why is the script not working in Mozilla?

Question

JavaScript

It works in other browsers, but not in mozilla, this is a script for minimizing the menu when scrolling down to the bottom.

The code

jQuery(document).ready(function($){

  // Top navbar animation
  // ------------------------------------------------------------------------
  $(document).bind('shrink-menu-init', function(e, status) {
    var topBarHeight = $('.navbar-extra-top').outerHeight(); // getting the height of the nabar-extra-top
    scrollMark = Math.max(topBarHeight, 30); // forced minimum of 30
    style = ".menu-shrink {top : 0px !important;}";
    if ( !$('#ShrinkMenu').length ) {
      $( "<style></style>" ).attr('id','ShrinkMenu').data('scrollMark',scrollMark).appendTo( "head" ); // add custom CSS for height offset
    }
    $('#ShrinkMenu').html(style);
  });
  // navbar adjustments on scroll
  $(document).bind('shrink-menu', function(e, status){
    scrollMark = $('#ShrinkMenu').data('scrollMark');
    // when scroll hits height of navbar top, apply style changes
    if ( $(this).scrollTop() < scrollMark ) {
      $('#MainMenu').removeClass('scrolled menu-shrink');
    } else {
      $('#MainMenu').addClass('scrolled menu-shrink');
    }
  });
  // trigger shrink-menu on scroll
  $(window).resize( function(){
    $(document).trigger('shrink-menu-init');
  });
  $(window).scroll( function(){
    $(document).trigger('shrink-menu');
  });

    // Sub-navbar affix on scroll
    // ------------------------------------------------------------------------
    if ($('#SubMenu').length) {
        $('#SubMenu').affix({
            offset: {
                top: function () {
                    return $('#SubMenu').parent().offset().top - $('#navbar-main-container').outerHeight();
                },
            }
        }).css('top',$('#navbar-main-container').outerHeight());
        // Update values on window resize
        $(window).resize( function() {
            theTop = $('#SubMenu').parent().offset().top - $('#navbar-main-container').outerHeight();
            $('#SubMenu').data('bs.affix').options.offset = { top: theTop };
        });
    }

    // accordions - always have 1 panel open
    // ------------------------------------------------------------------------
    if ( $('.panel-heading').length ) {

        $('.panel-heading').on('click',function(e){
            if($(this).parents('.panel').children('.panel-collapse').hasClass('in')){
                e.preventDefault();
                e.stopPropagation();
            }
        });
    }

    // Tooltips
    // ------------------------------------------------------------------------
    $('[data-toggle="tooltip"]').tooltip({
        placement: function(tip, trigger) {
            // show above, unless no space. show bottom on affixed sub-nav
            return ( $(trigger).parents('#SubMenu.affix').length ) ? 'bottom' : 'auto top';
        }
    });

    // owl carousel
    // ------------------------------------------------------------------------
    if ( $('.featured-carousel').length ) {
        $(".featured-carousel").owlCarousel({
            items: 1,
            loop: true,

                '<i class="fa fa-angle-right"></i>'
            ]
        });
    }

    // Things we want to trigger once, forcefully, after loading the page

    // Fire the menu shrink function

    $(document).trigger('shrink-menu');
