I managed to find a working solution using __event method from the MozRepl::RemoteObject module... I basically get the td node and call JS events on it.

my @el = $mech>by_id('mytd');
$el[0]->__event('mouseover');
$el[0]->__event('click');

This works but I m wondering if this is a good solution or there are better alternatives. I read a Corion post where he suggest to capture get/post http request uri and directly use them with ->get()
