jQuery not Working in Fire Fox

jQuery not Working in Fire Fox

I have been to a few Web Development forums, but no one seems to be able to help me. Fire Fox is not running jQuery in any form or fashion. It gives me the following errors:

Here is my code:


  2. $(document).ready(function(){
  3.     $('#filterBox1').change(function() { // when value of filterBox1 changes
  4. var selection = $('#filterBox1 option:selected').val(); // get it's value
  5. if (selection == 'Windows') { // if windows is selected from OS
  6.              $(".tb-container:not(:has(img.windows))").hide(); // Hide all DIVs that do not contain img.windows


  8.         }
  9. if (selection == 'Mac') { // if mac is selected from OS
  10.              $(".tb-container:not(:has(img.mac))").hide(); // Hide all DIVs that do not contain img.mac
  11.         }
  12.     });
  13. });
