I have ticked autofill addresses but not autofill payment info but Firefox autofilled my credit card details on a site that I would not give my credit card details to, how do I stop this in future? I wanted to see how much they would charge for shipping so I had to put in my address and I allowed it to autofill but then it put in my credit card details. I do not give my credit card details to sites that I am unfamiliar with, I will use PayPal instead and this site then captured my details and sent a SMS to my phone to confirm so I know that they have captured some of my details, probaby my credit card details as well. I went to settings assuming that the settings may have changed in the last update of Firefox but there is still no tick in the box Save and autofill payment info. I want to delete my credit card details from Firefox but I can't find them. There is nothing at all under payment methods and under addresses there is no record of my credit card. I wanted to send this to Firefox as a bug report but I can't see how to do that. Perhaps you could send a bug report for me.
