I have credit card auto-filling enabled and several credit cards active. However, most of the time, when I go to use the autofill, though the card choices appear and I am able to select one, and it usually temporarily shows the fields to be filled, when the menu closes, the auto-fills are gone! It's worse than not having autofill at all. This seems to happen the majority of sites where I try to use it.

When I click to fill in a Credit Card field to pay for something, my correct card info appears momentarily, but then disappears. To execute a payment, I am forced to manually fill in all required information. I made sure the "save autofill" box was properly checked in the Settings, and it was. Names, addressed, etc. are all filled in properly; only credit card info is not.

All my attempts to pay online with 2 out of my 3 cards have failed in the last 2 weeks. The Mastercard says it has connected to my bank and I'll get an SMS - but the SMS never arrives, and when I phoned my bank, they said they had no authorisation attempts reach them at all! The Visa card simply says it failed at the first step, without saying why or serving up the usual security dialogue. (The other Visa card just works).

I suspect the Autofill may be the problem here. I've recently had other scenarios where FF filled in a field for me, but the Javascript behind the website refused to accept it, eg saying it wasn't a valid phone no when it clearly was. The only way to get round this seems to be to type in the complete value yourself, which rather defeats the object. It could be something else, but it's clearly dependent on which software's running behind the card, as the third card succeeds.

The autofill card details isn't working. When I try to I get the message "You have no saved cards."

When I go into the Privacy & Security tab I can see that I have a number of cards saved correctly.

Firefox autofilling my freaking CC number though those settings are disabled. I want to know what Firefox file my CC number is stored in.

Give me the filename -- I'll do the rest...

I have some names that pop up in an autofill dropdown when trying to input names. Some of them are misspelled and some are obsolete. How do i delete these? I've looked in Privacy and Settings and they are NOT present under "Addresses and more". Those are complete addresses with names. The ones i'm referring to are just names that pop up in an autofill drop down. These are names that i can't seem to find anywhere in Settings.

I came across another thread here that said try highlighting the name and Shift+Fn+Delete. This does not work

Thanks in advance.

I need to edit the phone number Firefox uses to autofill forms. Sometime in the past, I accidentally entered one incorrect digit in my phone number, and now Firefox wants to send verification codes to that number.

The summary says it all. Some time in the pas few days, my saved payment methods disappeared. If I try to use Add new payment method, enter my information and then save, the same things happens. It just disappears as if I hadn't done anything. Any suggestions on why it's suddenly refusing to remember my payment info?

I have card data saved for a number of cards in Firefox, and I am looking to clean that data up. However, when I go to Settings>Passwords and autofill>Payment methods>Manage payment methods no cards are showing up as saved. I also know that this is not Lastpass causing issues, as this card data is not saved in Lastpass. I have attached screenshots of both the manage payments page and the card data showing up for autofill selection on a webpage add payment method screen.

Shopping with an online vendor I have never contacted before, using fully updated Firefox on Win 11 Pro and ESET, the website checkout offered a "Buy with SHOP [visa] ####" blue button. '####' is the last four digits of a credit card of mine.

I did not realize until later "Buy with SHOP [visa] ####" meant "Shopify" would own the transaction. I have never established any online "Wallet" and would never do that. I had never heard of "Shopify." I did not know what it is. Now I do, and I am terrified. I have the complete source code from the page. If that would help a diagnosis, let me know. It is clear that Shopify populates the form from information it already has; how they write the HTML is less important than how they got this personal information in the first place.

Is there a setting in Firefox that allows this? If so, how can I disable it? IF Mozilla has distributed an "update" that defaults a wallet to "ON". please tell me. Tell me in simple terms how to shut all this garbage off so it stays off.

My credit card company, Chase, has Excellent Security and no charge from Shopify will be paid, ever. But what other data does Shopify have and how did they get it?

Thank you for your help. Very much!

Hello, lately when making a purchase the autofill feature for payment is not functioning properly for me. The account numbers appear for selection as normal, and the pop up window that asks for password or fingerprint ID, but it will not select and fill in the data. It doesn't matter whether I choose to use the fingerprint or type in the password. I hope you can help as this is most convenient. ;-) Many thanks

I use Firefox for Linux on a Lenovo ideacentre desk top and on an Android mobile (Google Pixel). I live in the UK. I've saved my debit card details on both devices and autofill works perfectly on my phone but won't work on the PC. I've checked settings multiple times and everything seems to be properly set. I've just checked (via about:config) that my regions supports autofill and it does. When I try to use autofill, my card details appear in a box but when I click on the card number to fill the details, nothing happens! I've tried disabling the extensions I normally use on the desk top (Privacy Badger and ClearURLs) but that didn't resolve the problem. Any help would be appreciated.
