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.
This situation was revolting in every way. They destroyed the best european tech company. They had everything. A music service, a maps service superior to Google Maps, mail service, everything. It was sickening.
