Payment method autofill stopped working
Payment methods are present and are offered for autofill, but the autofill never actually happens. The dropdown correctly shows the last 4 digits and expiration date of payment methods.
The dropdown autofill offer closes when I click on one of the payment methods, but the fields aren't actually filled in. Hovering on a payment method in the dropdown does show the method filled in, but the fields revert to empty if I choose any of the options or try to move the cursor elsewhere.
This happens in private windows too with all extensions disabled.
Passwords and logins are autofilled correctly.

So besides the general info in the other threads, on Linux the issue is usually in the system keyring that the encrypted credentials rely on the secret to unlock, and it's apparently getting inaccessible between unlocks: https://bugzilla.mozilla.org/show_bug.cgi?id=2026488
