Can you provide a screenshot showing the entire browser? That screenshot only shows what's in the browser. Did you try in safe mode? Are you running any virus or security software?

tried safe mode. no antivir, no secure, no firewall. only w10.

How about checking your cookies? Maybe there is something blocked that is preventing the cart from showing. Let block all cookies and see what happens.

I can reproduce your issue with cookies blocked. see screenshot

the option helped - clear firefox. now everything works. thanks.

Similar problem - after last (as i think - big) update (interface update and etc); before it all works fine. Reset site options not works (but i still not trying clear all cookies for all sites in settings, coz it some problem for me right now)

full profile cleaning helped. but the cart is not displayed correctly. postage only appears after viewing favorites.
