Answer 1

Check offset every time you scroll the page

$(document).scroll(function() {
    checkOffset();
});

function checkOffset() {
    if($('#social-float').offset().top + $('#social-float').height() 
                                           >= $('#footer').offset().top - 10)
        $('#social-float').css('position', 'absolute');
    if($(document).scrollTop() + window.innerHeight < $('#footer').offset().top)
        $('#social-float').css('position', 'fixed'); // restore when you scroll up
}

and make its position absolute if it has been downed under 10px before the footer.

Try this, It will check if you are reached to bottom and set the FixDiv position to relatve, May be it helps you

jQuery(function($) {
  function fixDiv() {
   var $cache = $('#block-dailydeal-news');
  var $cache1 = $('.footer-container ');
  if ($(window).scrollTop() > 100)
    $cache.css({
      'position': 'fixed',
      'top': '0px',
      'z-index':'100000'
    });
  else
    $cache.css({
      'position': 'relative',
      'top': 'auto',
      'z-index':'auto'
    });
   }

   var hT = $('.footer-container').offset().top,
   hH = $('.footer-container').outerHeight(),
   wH = $(window).height(),
   wS = $(window).scrollTop();
   if (wS > (hT+hH-wH)){
     $cache.css({
      'position': 'relative',
      'top': 'auto',
      'z-index':'auto'
    });
   }

  $(window).scroll(fixDiv);
  fixDiv();
});
