Mozilla announced that they will stop developing Firefox OS for smartphones and selling phones with this operating system . The development is still going and Firefox Marketplace will still work as its working now. * An official confirmation of Firefox OS discontinuation has been given by Ari Jaaksi, who is a SVP of Connected Devices at Mozilla. '''We are proud of the benefits Firefox OS added to the Web platform and will continue to experiment with the user experience across connected devices. We will build everything we do as a genuine open source project, focused on user experience first and build tools to enable the ecosystem to grow. Firefox OS proved the flexibility of the Web, scaling from low-end smartphones all the way up to HD TVs. However, we weren’t able to offer the best user experience possible and so we will stop offering Firefox OS smartphones through carrier channels. We’ll share more on our work and new experiments across connected devices soon.'''
