Ordering in firefox, product showed in chrome

[kriss-ns]

Hi,

I have a weird behaviour when making an order. I order in Chrome, and when I refresh the page in Firefox i can see what i have ordered in Chrome. I am not logged in nor registered.

Is this normal behaviour?

Joomla  2.5.25
VM: 2.0.24c

joomla cache plugin enabled? It MUST be disabled! and you should update your joomla and vm asap

cache plugin is OFF 

Another problem only on safari, iphone, when a product is ordered something else is in the cart, and it can not be removed.
