I'm using submodal-1.6 for popup.

When the popup closes I wanted parent page to refresh.I've tried the following
window.opener.location.load();
location.load();
window.parent.location.reload();

All works for IE, but when coming to mozilla ,firefox the refresh is a step delayed, i.e when I open my popup to add an itme to my cart on parent page ,for the first time it does not show anything , but when I try to add another item , the first one shows.

Any advice would be really great.
