As requested by the engineering team, I've retested this in the latest Nightly 132.0a1 on Windows 10 x64. * The Cardholder Name field is not cleared when the autofill is triggered in the Card Number or Expiry Date fields. * The Cardholder Name field is not being previewed when using autofill in the Card Number or Expiry Date fields. * The Cardholder Name field is not highlighted when using autofill in the Card Number or Expiry Date fields. * The Cardholder Name field is previewed, autofilled, and then cleared individually when using autofill in this Trigger Field. The 'Name on Card' 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). Setting the pref extensions.formautofill.heuristics.autofillSameOriginWithTop pref to true resolves the issues. Please find attached the Field Info section details from about:autofill.
