Works fine in Chrome but not in Firefox

Hi, I have the below code that works fine in Chrome to highlight the selected/clicked item but doesn't highlight it in Firefox.
any ideas why?

$(document).ready(function() {
   var app_id = $('#P0_MY_ID').val();
   $('#report_APP_ID table tr input[value="'+app_id+'"').parent().parent().children().css('background','#3399FF')
   $('#report_APP_ID table tr').click(function() {
      var hiddenVal = $('input[name=f23]', this).val();
      window.location = 'http://mydomain:6767/ords/f?p='+$v('pFlowId')+':2:'+$v('pInstance')+':::2:P0_MY_ID:' + hiddenVal;
   });
});

Select allOpen in new window

when the user clicks on the row of the table it redirects to the same page and sets the variable that I use to highlight the clicked row.
Is there a better way that allows FF to work also?
Thanks, Bill
