I also notice that if I use the modern cart with the ajax (well I think its ajax) summary once you select the domain, it is not loading properly or takes ages and in Firefox 13 the order summary is not loading at all (it is empty) and therefore I cannot click the checkout. Although it is working in Chrome but takes a little while to load and then there is a delay when I click the checkout button.?
Yea, I experience the same issue with Firefox. Just my order does not go through at all selected on the modern cart especially.
Please advise !!!!
