Nice to see that there are efforts but until they can roll it out as a core feature with prompts/nudges it's not going to cut it and I'm not entirely sure they have the market/mind share to pull it off these days. Pateron came out in 2013 and has strong community/network effects now, YouTube Red/Spotify also address much the same problem. The current state of affairs is like their idiotic mobile 6 full years after the iPhone came out and at a time when Android/iOS had already won and Microsoft efforts already imploded.
If they rolled out a payment option for third-party sites as a core feature with prompts and nudges, do you really think the reception would be positive? I expect the comment threads would be full of people telling Firefox to work on being the best browser they can, and not getting in people's way with a payment system that "nobody asked for".
I think that would depend a lot on how it's done. If it were simply a mediator/platform that could be opted-into by the serving site kind of like a pateron ad/button I think that could go a long way. The value-add of pateron being in intermediating the transaction and collecting/collating my top interests in a privacy conscious way.
