We have migrated our jQuery to 1.6.3 to 3.3.1 which has led to browser issues. 

1) _doPostBack :  The below code works fine and post backs to the event in Chrome, Edge, IE but not in Firefox. I'm not getting any error messages as well. However, when I remap jQuery to 1.6.3 post back is triggered. Not sure what the issue is. 

__doPostBack($('div.tree-view input.update-button').attr('name'), 'ItemChecked') 

Any helps would be helpful.
