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.
It was a very good concept, but sadly rolled out on too shitty hardware so it never caught on.
I have a de-googled LineageOS (absolutely no google packages or play services installed) with microg and Aurora Store. I use N26 and it works fine.
Aurora still works, but the anonymous accounts are all broken. They get throttled because of too many requests on the accounts which need to be manually generated.
I believe it works fine if you log in.
Does Aurora still work? Last time I tried to degoogle completely, no store alternatives worked, Google seems to have their thumbs on them very effectively.
I’ve been using Aurora on CalyxOS with no issues.
