Three comments:

1. The site almay.com doesn't seem to support non-US addresses. Is the region for this bug incorrect? The site does fill in the state correctly when a US state is available.
2. Both the first name and last name input fields have the same form field name 'shippingFirstName'. The field that is intended to
   be the last name field is filled in with the first name instead. Despite the web site error, Chrome fills the names in correctly. Perhaps we should handle this case by using the first field with that name as the first name, and if there is a second field, use it for the last name. It is a likely a bit of code to add for this edge case however. The billing section works correctly for me.
3. To investigate: why the autofill doesn't occur for the email field.

Hi Neil, do you mean we do recognize both the name fields, but we treat both of them as "name" instead of "given name" & "family name"?
If yes, there are two solutions for this issue:

1. Check the markup to see if we are able to classify the first name and last name correctly by adding missing keywords in
   https://searchfox.org/mozilla-central/rev/0e9ea50a999420d93df0e4e27094952af48dd3b8/toolkit/components/formautofill/shared/HeuristicsRegExp.sys.mjs

2. Add a _parseNameFields in https://searchfox.org/mozilla-central/rev/0e9ea50a999420d93df0e4e27094952af48dd3b8/toolkit/components/formautofill/shared/FormAutofillHeuristics.sys.mjs#564-570 that when we see consecutive two "name" fields, we update them to "given-name" and "family-name"

Yes, we treat both fields as 'given-name'. If I manually modify the second form field to be 'shippingLastName' instead, then autofill works for the both name fields correctly.

The id and placeholder attributes on both fields is correct, just the name is incorrect.

Originally i thought if we see two same consecutive name fields ("name, name", "given-name, given-name", or "family-name, family-name"), we could just update the two fields to "given-name" and "family-name". But then i realized that this will not work for countries that put "family-name" before "given-name". I'll have to think about whether there is a better solution.

One approach we might consider is when we see consecutive name fields are identified with the same field name, such as first name + first name or last name + last name. We could treat the two name fields as name-1 and name-2. During the capturing or autofilling process, we could first check if the captured or autofilled name is a CJK name. If it is a CJK name, we would treat name-1 as the family name and name-2 as the given name. Conversely, if it is not a CJK name, we would treat name-1 as the given name and name-2 as the family name.

Verified - Fixed in Nightly 134.0a1 (2024-10-30). All the Address fields are autofilled accordingly now, except the APT field which is not autofilled, but the second line of the saved address is added to the Address field (see the video attached in comment 10).

APT field issue.
