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.
Neurodivergent people can be extremely particular about things people don’t even think of and will get anxiety if they’re not as they’re supposed to (seldom ever whimsical, mostly when stuff doesn’t make sense).
