I have a customer that is uncomfortable placing an order with us on the web store. He placed his first order OK. He went back to place a second order and his Fire Fox web browser automatically filled in his credit card information.

He says that ours is the only site he's ever used that has this issue. He says it is "disconcerting."

I'm speculating that other sites generate random or trackable web addresses when the checkout process starts and this is why it doesn't happen on other sites.

Has anyone else experienced this? Is there something I can do on my end to prevent this "feature" from working on the customer's browser?
