title: Firefox not sending POST data to server
body: <p>I can't seem to send ANY data to the server. Even tough I can in some of the other pages that I have. The only difference is that I am using a file upload in this perticular form. All works well in chrome.</p>
  
  <p>Where is the error?</p>
  
  <pre><code>&lt;script&gt;
          $( document ).ready(function() {
              $("#addnewadform").submit(function(e){
                  e.preventDefault();
                  $.ajax({
                      cache:false,
                      url: "/call/insert-standart-add.call.php", //URL IS CORRECT
                      type: "post",             // this is OK too
                      data: {submitStandartPost:'im sending the submit button value'}, //this is a super-simplified version of what i want the server to recieve
                      contentType: 'multipart/form-data',//i have tried a ton of different values for this
                      processData: false, //think this should be false for file uploads
                      success: function(data){
                          console.log(data);
                          if(data!==''){
                              console.log(data);
                          }else{
                              console.log("nothing was sent");
                          }
                      }
                  });
  
              });
          });
      &lt;/script&gt;
  </code></pre>
  
  <p>The server does not recieve anything, but the script itself is being called.</p>
  
  <pre><code>if(isset($_POST['submitStandartPost'])){
  
  }else{
   echo 'no input';
  }
  </code></pre>
  
  <p>maybe the error has nothing to do with file upload. I have tried to remove the file upload and enctype='multipar/bal bla bal'. just does not work. No errors being logged</p>
