Try this code

$("#send").on("click", function(e) {
e.preventDefault();
$.ajax({
            type: "POST",
            url: "ads_process.php",
            //Specify the datatype of response if necessary
            data: $("#ads").serialize(),
            success: function(data){
                if(data == "true") {
                    $("#ads").fadeOut("fast", function(){
                        //$(this).before("<p><strong>Success! Your message has been sent, thanks!</strong></p>");
                        setTimeout("$.ads.close()", 2000);
                        });
                    }
                }
            });
        });

By using prevent default you can stop the form refreshing the page like so: http://api.jquery.com/event.preventDefault/

$("#send").on("click", function(events) {
    events.preventDefault();
    $.ajax({
                type: "POST",
                url: "ads_process.php",
                data: $("#ads").serialize(),
                success: function(){
                    if(data == "true") {
                        $("#ads").fadeOut("fast", function(){
                            //$(this).before("<p><strong>Success! Your message has been sent, thanks!</strong></p>");
                            setTimeout("$.ads.close()", 2000);
                            });
                        }
                    }
                });
            });
