1783194 - Firefox thinks that the card number field on cibc.com is a credit card number field

Status: RESOLVED DUPLICATE of bug 1788621

(Toolkit :: Form Autofill, defect, P3)

Description

[Jeff Muizelaar [:jrmuizel]]

Firefox prompts to fill in my credit card number on https://www.cibconline.cibc.com/ebm-resources/public/banking/cibc/client/web/index.html#/signon

When I log in wants to create a new credit card for my debit card.

I did not used to see this behaviour and Chrome also does not have this behaviour

hi janika, could you help take a look at this bug? Thanks!

Comment 2

You can save your credit card number and password via about:logins first. The login form will then be autofilled and after login it will not ask you to create a new credit card. This at least works as a temporary solution.

Is it worth trying to get a regression window?

Comment 4

[Janika Neuberger [:janika]]

Hi Jeff,
we already detected the regression window. The issue is caused by the patch for Bug 1775233. We hope by optimizing our machine learning algorithm Fathom, that is detecting and categorizing the different form input fields, that problems like this issue will be solved as well.

The input#card-number-5e6602ab field meets the following rules from the creditCardRuleset of type cc-number:

1: hasTemplatedValue → 0
2: idOrNameMatchDwfrmAndBml → 0
3: idOrNameMatchSubscription → 0
4: ariaLabelMatchesGift → 0
5: placeholderMatchesGift → 0
6: labelsMatchGift → 0
7: idOrNameMatchGift → 0
8: ariaLabelMatchesNumberRegExp → 0
9: placeholderMatchesNumberRegExp → 0
10: closestLabelMatchesNumberRegExp → 1
11: labelsMatchNumberRegExp → 1
12: idOrNameMatchNumberRegExp → 1

Fathom calculates a 0.9999536363015451 probability that this is a cc-number (>threshold).

I also see this bug at https://auth.scotiaonline.scotiabank.com/online

This is happening again. Should I open a new bug?

Comment 10

[Dimi Lee [:dimi]]

Hi Jeff, thank you for reporting this issue,
The issue is happening again because Bug 1792544. Firefox now always honor the autocomplete attribute set by websites.
The markup of the card number field is

<input id="12-field" type="text" name="cardnumber" maxlength="19" aria-describedby="vue12-messages CardTypeIconId-11"
aria-invalid="false" autocomplete="cc-number" data-test-id="card-number-input" error="false" class="">

Because it has autocomplete="cc-number", Firefox treats it as a credit card number field.

If the field has autocomplete="cc-number" it seems reasonable for Firefox to always honour it.
