autofill credit card fails

Hi

Do you have any add-ons installed in Firefox?

Did you install Firefox from the Windows App store?

No add-ons. Extensions: DuckDuckGo Privacy Essentials Facebook Container Open Link with New Tab Tab Reloader uBlock Origin

No, Firefox was installed before I knew about any Windows APP Store.

To clarify, that is a list of add-ons.

Please can you try installing them all and trying the payment card again.

Where did you install Firefox from?

They are already installed.

I installed FF many years ago. I think I installed it from Mozilla I have been using it "forever"

Is it happening on all sites, or just a specific one? (Would you mind sharing your country, as the autofill logic differs e.g. between US and UK…)

You can try autofilling some of Mozilla's testing forms to see if at least these work as expected.

If you open https://mozilla.github.io/form-fill-examples/ there's several variants in the top "Forms" section — if you click through the links, some will have credit card fields to test. This is just a dead form that will not pay for anything or send the data anywhere;) it's only for Mozilla testing to see how different types of forms handle the autofill input. It also includes some very simple forms to verify your autofill even works on these. Basically all of that is used in Firefox testing, so these are believed to be working with your credentials — if not, there's something off, because these "should just work".

These forms are safe and do not send your data anywhere, everything stays just in your browser, there's no "server" component that would be able to listen, these fields are statically served and only used for heuristics and testing. (If you don't feel like autofilling your real card, you can add a "4242424242424242" Visa with any future expiration to your payment methods for testing.)

I am in the US (Tennessee) I have not been to any sites that have this problem. Other sites like Amazon have my CC on file. Here are the results from the form-fill-examples:

• Basic address form using @autocomplete Two addresses, both fill and accept Submit.
• Basic credit card form using @autocomplete. Not good. Click in Name drops down my two CCs, Hover over each in turn shows correct last 4 and puts the name in the Name field. Click on either one and all fields go empty. Same for the other fields. For example if I click in the Expiration field and hover over one of the CCs all fields are filled correctly. Bit if I click one of them the fields go empty.
• Basic U.S. form using @autocomplete Works fine.
• Including all supported @autocomplete. Address area works fine. CC not good, Just like Basic CC. Login and Registration do nothing.
• The others work fine except for the two that start Credit card. They are bad just like Basic CC

Do you want me to keep going?
