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.
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.
