The confirm_cart page has the same .js files as view-cart, but the remove link doesn't work. What cart .js file are you referring to?
Also, you have added "stripe-php/init.php" to the confirm_cart page so I'm concerned that changes I make are going to upset the Stripe integration.
I attach that file.
EDIT: Is it not working because it isn't within this form:
<form action="<?php echo ($_SERVER["PHP_SELF"].(isset($_SERVER["QUERY_STRING"])?"?".htmlentities($_SERVER["QUERY_STRING"]):""));?>" method="post">
