On a clean install of CE 1.9.3.3, multishipping is broken when using the default theme and enabling checkout form key validation.
How to reproduce:
- Change the theme from
rwd
todefault
- Enable the
Enable Form Key Validation On Checkout
setting - Add a product to the cart and go the
checkout/cart
page. - Click on "Checkout with Multiple Addresses" to go to the
checkout/multishipping/addresses
page. - On this page, observe that the following buttons do not have any effect:
- "Enter a New Address"
- "Update Qty & Addresses"

This issue is also present on previous Magento versions with SUPEE-9767 installed.
