Mozilla first unveiled its Firefox OS back in 2013. The company was mainly targeting the developing world and people looking for low-cost handsets. It tried to differentiate itself from its chief rivals the Android and iOS by becoming a web-first mobile OS; it had no native app but only web apps.
Well, that didn’t work out so well for the company and sales have always been poor. Not only did the smartphone running Firefox OS fail to ignite some interest among consumers, but also the market was already flooded with cheap handsets running Android OS. In an industry that depends on economies of scale, Firefox OS never really caught on and became a thing, and the company was spending more that it was getting as revenue from the business.
