I use it as my primary phone for 2 years, first with the Flame, then with a Z3C.
For me Firefox OS was the finale move of Mozilla, either it successes and Mozilla becomes a major actor again or it fails and they slowly die. And thebmy decided to kill it right when it was becoming stable enough.

A big part of the market share loss was due to monopoly and distribution lockdown of a controlled platform tightly tied to hardware, so I can certainly see the strategic wisdom of the attempt. I suspect they didn't have the resources to press forward, they had a lot less money then than they do now. Which makes it all the more maddening that Yahoo's role as a partner was so muted; it could have made the difference for both of them.
