I've retested this on the latest Nightly 132.0a1 on macOS 14. * Triggering autofill from “CC number” and “Date” fields isn't autofilling "CC name" field * Clearing autofill from “CC number” and “Date” fields isn’t clearing “Name” field * Triggering autofill/clearing from “Name” field is only autofilling/clearing “Name” field When the extensions.formautofill.heuristics.autofillSameOriginWithTop setting is set to true, clearing autofill from any field is clearing all the targeted fields, but not if the triggered from "CC name" field. The "CC Name" field is situated on the main page, and not inside an iframe, unlike the 'Card Number' and 'Expiry Date' fields which are located within same-origin iframes.
