Question

what’s weird about my error is that it ONLY occurs in the firefox extension I have linked to at the bottom of this post. I cannot reproduce this error in any other setting.

I have this ajax request

$.ajax({
  type: "GET",
  dataType: "jsonp",
  url: url,
  jsonpCallback: "JSONCallback",
  data: {title:$("#txtTitle").val(), url:taburl},
  success: function(data, textStatus) {
    if(data.code > 0)
        {
        $("#icon").removeClass().addClass('accept');
        }
    else
        {
        $("#icon").removeClass().addClass('error');
        if(data.code == '-1')
            alert('kunne ikke finde din ønskeseddel på e-ønsker.dk - besøg e-ønsker.dk, og prøv derefter igen');
        }
  },
  error: function(xhr, textStatus, errorThrown) {
     alert("XMLHttpRequest="+xhr.responseText+"\ntextStatus="+textStatus+"\nerrorThrown="+errorThrown);
    $("#icon").removeClass().addClass('error');
  }
});

server returns

JSONCallback({"code":405});

headers are application/json

so why am I getting a parseError saying JSONCallback was not called? I thought jQuery was supposed to handle that for me?

the code is from http://builder.addons.mozilla.org/addon/1022928/latest and the file in question is data/panel.js

The problem is with window. The easiest way to fix this will be to edit the jQuery code (I know, I hate doing this too) to use unsafeWindow rather than window.
