Credit card authorisation failing with Autofill

Firefox Autofill

All my attempts to pay online with 2 out of my 3 cards have failed in the last 2 weeks. The Mastercard says it has connected to my bank and I'll get an SMS - but the SMS never arrives, and when I phoned my bank, they said they had no authorisation attempts reach them at all! The Visa card simply says it failed at the first step, without saying why or serving up the usual security dialogue. (The other Visa card just works).

I suspect the Autofill may be the problem here. I've recently had other scenarios where FF filled in a field for me, but the Javascript behind the website refused to accept it, eg saying it wasn't a valid phone no when it clearly was. The only way to get round this seems to be to type in the complete value yourself, which rather defeats the object. It could be something else, but it's clearly dependent on which software's running behind the card, as the third card succeeds.

There certainly are sites coded in a way that any autofill is "unexpected" to them. Usually the same is with pasting into their fields. They might want to reformat the input, or need a keypress (an extra space, or delete and retype the last digit etc.) to trigger their mask, or inline validation to even see the format of the value entered.

However none of that should mean a card gets accepted, but a) your two–factor trigger from your bank never happens, or b) the card gets declined. Are you sure you haven't forgotten to update any card details when reissued the last time, or your CVC/CVV isn't different?
