After I buy stuff from websites (Blue or Green Website ID) and I go back to the site it has remembered the credit card numbers from last time. I would like Firefox to remember other parts of the form/purchase sheet, but not the fields for the credit card details (and any other field type I would like to not be saved). Is there a way to only delete these fields without going back to the page and selecting the field entry to delete as I don't remember all the sites/pages that the numbers would have been saved on? (it would also require me to go through a fake purchasing process to get to the page the details are saved on) It would also be good if it can have an auto-detection thing to pop-up when you are about to enter your credit card details and you could use your mouse to enter the details. In case there is a key-logger on the computer. CreditCardNanny does add a little bit more security.
