I would like the feature, like chrome has. That it lets you save your address and your credit cards, so after when i go to payment on a website, it would suggest me if i want to autofill it with the saved addresses and credits cards I have. Its very useful, especially went i want to buy/pay something quickly and i just do 1-click autofill my credit card number, expired date, so I don't have to remember it. Same goes for addresses. Much faster and easier.
