I am able to reproduce this issue. Navigating to the site in Firefox Android takes us to an extra page before getting to the mobile site. Chrome is sent right to the mobile site for me. Spoofing the user agent as Chrome in Firefox, also takes us right to the mobile site.

This is the problem, right in their index.html:

  checkAndroidSize: function () {
    var index = navigator.userAgent.indexOf("Mobile Safari");
    if (index == -1) return "Tablet";
    return "Phone";
  },

This function is expected to return "Phone" for the redirect to work. The check is rather strange, as it's not based on screen size at all, but if they only want Chromium and Firefox for some reason, then they can use this instead:

  checkAndroidSize: function () {
    var phone = navigator.userAgent.indexOf("Mobile Safari") > 0 ||
                navigator.userAgent.indexOf("Firefox") >= 0;
    if (!phone) return "Tablet";
    return "Phone";
  },
