An anonymous reader writes: Mozilla announced today at its developer event in Orlando that the company is ending its smartphone experiment. Mozilla will stop developing and selling Firefox OS smartphones. Ari Jaaksi, Mozilla's SVP of Connected Devices, said, "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." However, he added that it didn't end up providing a great user experience, so they decided to move their efforts elsewhere within the "connected devices" ecosystem. The TechCrunch article notes, "Mozilla has been on a streamlining track lately. Last week it announced that it would be looking for alternative homes for its Thunderbird email and chat client. The aim is for the company to focus more on its strongest and core products and reputation."
