A form is autofilling name address phone, fair enough, it's not remembering card number, good, but it IS remembering the CVV which is very bad.

I don't understand how this is controlled, and I can't see anything in the page source

Is there something I can do about it, or the page owner can do?

Thanks

Firefox will store autocomplete data if the input field doesn't have an autocomplete="off" attribute.

Firefox can recognize some specific data like credit card numbers via a check like the Luhn algorithm and omit storing such a number.
