Firefox OS was a mobile operating system by Mozilla that was launched to market on 2013 by Telefónica. The Firefox OS for mobile devices was built on Mozilla’s “Boot to Gecko Project”, which unlocks many of the current limitations of web development on mobile, allowing HTML5 apps to access the underlying capabilities of a phone, previously only available to native apps. Telefónica’s Digital unit joined forces with Mozilla to take this work and showcase a new phone architecture where every phone feature, like calling, messaging, games, etc. is an HTML 5 app.
