$('.versionSelectWizardCoti').live('focus',function() {
currentValSelect2 = $(this).parent().parent().parent().attr('id');
$(this).blur();
});
The .blur() call works in IE7+ and Chrome, but does not work in FF 8.0. The select element freezes and shows nothing.
Try to change
$(this).parent().parent().parent().attr('id');to$(this).closest('your element class/id').attr('id');
