I'm trying to enable autofill for payment methods but autofill is not working. I've checked the correct box under Preferences --> Settings --> Save and fill payment methods. I do not need the device to require sign-in to do this. But when I try to fill in from my saved payment methods, nothing fills in. I've restarted Firefox and my MacBook Pro, but it still doesn't autofill the payment methods. This has worked in the past, but it's not clear why it's not working now even if I have followed all the correct steps. Please help! Thanks
