Autofill Credit Cards
I've searched and it told me that it was under Privacy and security. But only thing there is "Saved Addresses." Where can I find the Auto Credit Card fill?

On mine, it seems this feature was turned off. Here's why I think that. I went into the Advanced Configuration Editor:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.
(2) In the search box in the page, type or paste credit and pause while the list is filtered
The extensions.formautofill.creditCards.available preference is set to false.
If I double-click that preference to set it to true, then a checkbox for it appears on the Options page.
The checkbox controls the extensions.formautofill.creditCards.enabled preference.
I don't know why the default is to hide the credit card autofill feature. Maybe there is a blog post or help article about that somewhere.
Quote: Note: The credit card autofill feature is available starting in Firefox version 81 and is currently available only for en-US Firefox releases.
