ERR_BLOCKED_BY_CLIENT ajax function not working in chrome

When Adblock is active in chrome below script is not working in chrome. It shows error in console like this

jquery-1.7.2.min.js:4 GET http://example.com/advertisement/mult_select/30 net::ERR_BLOCKED_BY_CLIENT

jquery-1.7.2.min.js:4 POST http://example.com/advertisement/getCategoryFieldsList/30/0 net::ERR_BLOCKED_BY_CLIENT

I have tried also anti-adblock-killer.user.js. But still it is not working.

<script>
$(document).ready(function(event){
    
$('.category_1').live('change',function(){

var foo = []; 
var name = [];
$('.category_1 :selected').each(function(i, selected){ 
  foo[i] = $(selected).val(); 
  name[i] = $(selected).attr("myTag");
});

//$('.category_title_0').html(name[0]);
var str = (foo[0]).replace(/\,/g, '');
$(this).parent('div').nextUntil('#tit').remove();
var str2 = $(this).find('option:selected').attr('parent_id');
$.ajax({
url: "<?= site_url('advertisement/mult_select')?>"+'/'+str,
success:function(result)
{
$('.mul-select').append(result);
}
});
$.ajax({
    type: "POST",
    dataType: 'script',
    url: "<?= site_url('advertisement/getCategoryFieldsList') ?>"+"/"+str+"/"+str2,
    success: function(result)
    {
        if($("#"+str2).length > 0)
        {
            $("#"+str2).empty();
            $("#"+str2).nextAll('*').empty();
            $("#"+str2).html( result );
        }
        else
        {
        $('#dynamic_fields_div').append( "<div id="+str2+"></div>" );
        $("#"+str2).html( result );
        }
    } 
});

});

});
