## Description

Smart Autofill fills forms with plausible test data, so QA engineers stop typing "aaa / bbb / <a href="/" rel="nofollow">test@test.com</a>" into the same checkout twenty times a day.

What it does
<ul><li>Realistic identities — first names match the selected gender and the age group detected from the form. A passenger block labelled "Child 1" gets a first name actually given to children today, not to their grandparents.</li><li>41 countries — pick a profile country and names, addresses, phone numbers and postal-code formats follow: Turkish, Japanese, Brazilian, Indian, Saudi, German, British and more.</li><li>Multi-passenger forms — each block gets its own consistent identity instead of the same name repeated.</li><li>Stripe test cards — a searchable catalogue of the documented test numbers: success, declines, 3-D Secure, disputes, fraud, verification failures, and per-country cards.</li></ul>
What it deliberately does not do
<ul><li>It never checks a checkbox. Ticking an option would silently change the scenario you are testing, so consent boxes are left for you.</li><li>It only fills when you ask, by clicking the toolbar button or the popup. Nothing happens on page load.</li><li>It collects nothing, sends nothing, and makes no network request of any kind.</li></ul>
About the card numbers
<ul><li>The card numbers are Stripe's publicly documented TEST numbers (<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/cf1d900c2bb3eb7f255c19c2fc59b1dee454c54ec3b137d0835223255bad3694/https%3A//docs.stripe.com/testing" rel="nofollow">https://docs.stripe.com/testing</a>). They only work against Stripe test API keys and are rejected in production. They cannot be used to pay for anything.</li></ul>
