Mozilla originally launched Firefox OS with dreams of democratizing the smartphone: instead of closed platforms and apps, you'd have an open, web-based framework that anyone could work with. Alas, however, that vision wasn't meant to be. The organization has announced that it will "stop offering" Firefox OS phones through carriers, effectively putting an end to those phones as a whole. It's still willing to "experiment" with the software on smart devices -- they just won't be the kind of devices that make phone calls. The team just couldn't deliver the "best user experience possible" on a handset, Mozilla says.
