credit card number appears and then disappears in firefox autofill
I have credit card autofill enabled, because I do a lot of business online and it is very convenient. Maddeningly, it has started doing something I can't find a way to fix. I put the mouse over the box asking for a credit card number, the saved numbers pop up, I select one, and then the pop-up box disappears without filling in the credit card number. There has got to be a fix for this, but I cannot find it. Pls. advise...
I had this problem too - it turned out that even though the number appears when you hover, it is not actually in the list of stored credit cards if you check in settings, and has to be entered again. The solution was described here: https://support.mozilla.org/en-US/questions/1360287
