Today 10 years ago I went to Poland to buy a Phone with pre installed #Firefox OS on. The Phone was a Alcatel One, so very shitty. Two years later I installed Firefox OS on my Nexus 5 instead https://jeena.net/photos/111
It was a very good concept, but sadly rolled out on too shitty hardware so it never caught on.
Thats unfortunate ☹️ both of my banks provide a PWA, one provided a hardware 2FA device once I went in and told them my device is rooted
