As requested by the engineering team, I've retested this in the latest Nightly 132.0a1 on Windows 10 x64. * The Cardholder Name and Expiry Date fields are being previewed, autofilled and cleared out together * The Cardholder Name field is being previewed, autofilled and cleared out individually * After Form Clearance, the Cardholder Name and Expiry Date fields remain highlighted The 'Name on Card', 'Card Number' and 'Expiry Date' fields are situated on the main page, and not inside an iframe. Setting the pref extensions.formautofill.heuristics.autofillSameOriginWithTop to true doesn't resolve all these issues. * The Cardholder Name field is being previewed, autofilled and cleared out individually * After Form Clearance, the Cardholder Name and Expiry Date fields remain highlighted Please find attached the Field Info section details from about:autofill.
