I've tried Firefox OS and it feels on par with early versions of Android in terms of UI/UX i.e. it is bad, very bad. Plus poor performance, lack of any app ecosystem and operators are sticking it on sub par hardware. At the end of the day, poor user experience. All said and done, Firefox OS is just something developed markets don't want and emerging markets don't need.

When did you try it? It moves quite fast.

Furthermore, why do you say emerging markets don't need it? The other OSes do not work on low-cost handsets any more. Targeting that niche is a good idea as it gives the OS a chance to gain relevancy with users who won't be as picky as HN readers.

At every MWC when it launched to the public and pretty much every iteration since then. My company develops solutions for a telco that is one of the key backers of Firefox OS in developing countries.

Also Firefox OS is not backed by a multi-billion corporation. And developers don't get a real choice of language. So it's going to be worse for a long time. Plus all the usual problems of being the last to the market.

Firefox OS is yet another example of Mozilla apparently thinking that ideological purity alone will somehow entice users into adopting an otherwise average-to-bad software offering.

That isn't how reality works, though, obviously. Out of necessity, most users must place software usability and capability above ideology. Software like Firefox OS and Persona will never see serious adoption when they can't compete with long-established and more functional offerings at the most basic levels, even if these competitors may not be as "open".

It's an approach that doesn't work for Mozilla's offerings that are already well-established, either. Firefox has been hemorrhaging users ever since its developers stopped focusing on truly improving the user experience, and instead focused solely on copying the worst aspects of Chrome (the UI, for example), while neglecting to address the performance and resource usage problems that have long plagued Firefox.

Users need software that works. If that means using software that's "less open" or "closed", they'll do it without a second thought. Mozilla just happens to often be on the losing side of this reality these days. While "openness" can be beneficial, it needs to be in conjunction with software that's at least comparably good to its "closed" competitors. Firefox OS, Persona and Firefox are good examples of where this isn't the case, and how they're either seeing limited to no adoption, or how they're losing existing users.

I don't get your point about choice of language. The web has more choice of language than any of the mobile app ecosystems.
