We are currently only maintaining the DOM implementation, but we don’t plan on shipping it in a product at this point. That may change in the future, but we don’t have any concrete plans.

If this is indeed the case, shouldn't the platform-status page (https://platform-status.mozilla.org/) mark this as abandoned? Currently, the page seems to imply that this is being actively worked on and would eventually land in a future Firefox version.

No.

The current status reflects our position - and also what I said above. This work has not been abandoned.

Can you help me understand what this means? :

Sure. We often develop/prototype features that we don't immediately ship in products (Firefox and Fenix, for instance) - see our "intent to prototype" in our exposure guidelines: https://wiki.mozilla.org/ExposureGuidelines#Intent_to_prototype

(please see also the dev-platform mailing list for other prototypes)

We do prototypes to understand how things work, to see if the spec is any good, and to understand if a product is viable (or not!) from a privacy and security perspective.

An API is not a itself a "product": a product requires, for example, localization, dev tools support, possibly its own section in Firefox's preferences, etc. etc. So to get something into Firefox/Fenix proper (not just Gecko) means a large part of the company needs to be involved. We are still at the "prototyping phase"... that involves not just writing code, but also collaborating on the spec with our colleagues at the W3C (Google, Apple, Microsoft, and the payment industry etc.).

I wouldn't expect to see this in Firefox proper for maybe a year or two. However, that doesn't mean we are not actively working on it. If you check the W3C repository for the spec, you can see I'm actively participating in the discussions and we are updating the spec often based on those discussions:

https://github.com/w3c/payment-handler/
https://github.com/w3c/payment-request/

Hope that helps clarify things!

I'll just add that this is the right bug to track progress on this feature. All related bugs we fix will be reflected in this bug.

That does, thank you for the explanation.

As an aside, this seems like a good candidate to list here: https://mozilla.github.io/standards-positions/ unless that page is only for future features.

FWIW, I arrived at this bug from the platform-status page.

Seriously guys, this bug has been on the roadmap since 5 years back!

Mozilla have left W3C payment activity which BTW suffered from an extremely poor analysis of the problem space. W3C did not only take on payments, but the entire "checkout" scenario including:

1. Payment method selection
2. Collecting customer information (name, address, etc.)
3. The payment operation itself
   All of this was supposed to be performed through a single monolithic API and associated browser "chrome".

What has happened during the 6+ years this activity have been running?

#1 would require major payment pages redesign as well as a very high acceptance.
#2 is currently being deprecated. It is not even obvious that payments and gathering customer information is done in the same step.
#3 well, since the W3C deliverables must "By Definition" NOT compete or challenge the members' own offerings (including Apple and Google Pay), the only thing left are UNDERPERFORMING solutions of no or little interest to anybody.

The only browser-vendor left is Google. It would take a miracle to get this effort back on track. A fundamental problem is that the payment industry (particularly banks) do not participate in or fund open standardization. Another problem is that an application-specific API becomes very close to a "product" which is incompatible with application-neutral platforms like browsers.

I would be interested in implementing the PaymentRequest interface.
However since PaymentRequest is useless without concrete implementations, I would also implement FIDO Web Pay:
https://lists.w3.org/Archives/Public/public-payments-wg/2021Jun/0021.html

How do I proceed?

PaymentHandler have finally been ditched by the W3C:
https://www.w3.org/Payments/WG/charter-2021.html

"Payment Handler API and Payment Method Manifest do not yet have sufficient
cross-browser implementation experience to advance to Recommendation.
However, the implementation in Chromium browsers enables experimentation,
and for this reason the Working Group intends to maintain it as a Working Draft.
If the implementation landscape changes, the Working Group will revisit the question"

The next victim seems to be PaymentRequest itself:
https://www.w3.org/2021/08/02-wpwg-spc-minutes.html

"Rouslan: In the future we'd like to move closer to WebAuthn as an extension to public key credential
… it might take .5-1 year to make the translation
… and that would decouple SPC from payment request API and put it closer to Credential Management API"
