Ajax url request is not working in Firefox, but works in Chrome

Hello,
I have this code:

var script_url = "https://script.google.com/macros/s/sasasaj/exec";
function insert_value() {
     var url = script_url + "?=callback=ctrlq&name=" +name+"&email="+email+"&action=insert";
     var request = $.ajax({
	    url: url,
            method: "POST",
            dataType: "jsonp",
	    crossDomain: true
     });
};

On firefox i’m getting this error: error: [object Object].
On chrome i’m getting success.

Any help?

Don’t know and I can’t test it because it is incomplete. Can you try this so we can get better data?

var request = $.ajax({
  url: url,
  method: "POST",
  dataType: "jsonp",
  crossDomain: true,
  error: function(jqXHR, textStatus, error) {
    console.log('error in AJAX call...');
    console.log('jqXHR:', jqXHR);
    console.log('textStatus:', textStatus);
    console.log('error:', error);
  },
  success: function(data) {
    console.log('succes in AJAX call...');
    console.log('data:', data);
  }
});

Hi Kevin,

I’m getting:
error in AJAX call…
jqXHR: readyState: 4, status: 404, statusText: “error”.
textStatus: error
error: error

This is the url:

var url = script_url + "?name=" +name+"&email="+email+"&phone="+phone+"&location="+location+"&company="+company+"&package="+package + "&treatment=" + treatment + "&dekking=" + dekking + "&notitie="+notitie+"&bonus="+bonus+"&bonustimer="+bonustimer+"&action=insert";

Do you have a working example? A pen or a repo?
