Question

HTML:

<div class="container-fluid hidden-md hidden-lg">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <div  style="z-index: 1;" class="visible-xs visible-sm"><a href="index.html"><img id="bizviz_logos" src="resources/images/logoaccses.png"  class="img-responsive" alt="Responsive image"></a></div>
    </div>
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
             <ul id="menu" class="nav navbar-nav navbar-right">


<li class="dropdown">
          <a href="#" class="dropdown-toggle" id="menu_scroll" data-toggle="dropdown">Support <b class="caret"></b></a>
          <ul class="dropdown-menu">
            <li><a href="downloadtrailversion.html">Download </a></li>
            <li><a href="blogs.html">Blog</a></li>
            <li><a href="whitepaper.html">Papers</a></li>
            <li><a href="gallery.html">Gallery</a></li>
            <li><a href="documentation.html">Document</a></li>
            <li><a href="licenseassistance.html">License</a></li>
            <li><a href="submitproblem.html">Problem</a></li>
            <li><a href="videos.html">Videos</a></li>
            <li><a href="faq.html" class="dropdown-toggle">FAQ</a></li>
          </ul>
        </li>

             </ul>
        </div>
    </div>

JQuery

$(document).on('click','#menu_scroll',function(e){
                event.preventDefault();

                $('.navbar-collapse.in').animate({scrollTop: 100}, 250);

})

As in the previous one, I use jquery for scroll.when I click on the menu item (bootstrap mobile - toggle button) in my website header ... its working tone is in chrome, but it doesn't work in firefox (scrolling does not happen). Any help would be appreciated.

Try this code

$(document).ready(function () {

        // hide #back-top first
        $("#back-top").hide();

        // fade in #back-top
        $(function () {
            $(window).scroll(function () {
                if ($(this).scrollTop() > 100) {
                    $('#back-top').fadeIn();
                } else {
                    $('#back-top').fadeOut();
                }
            });

            // scroll body to 0px on click
            $('#topanimated a').click(function () {
                $('body,html').animate({
                    scrollTop: 0
                }, 800);
                return false;
            });
        });

    });

Set this id in the id = "back-top" button
