There isn't much to add. the proper paypal carts show up on all the Safari browsers on all our desktop and laptop models and folks can use them to buy tickets to shows at our non-profit theater. HOWEVER ... when I go to that page with Firefox MOST of the computers show the page but without the PayPal Carts ... WITH THE EXEPCTION OF MY LAPTOP. I don't know how to correct this and since it directly affects our ability to sell tickets I need to settle this very fast
