Intro
Firefox OS (project name: Boot to Gecko, also known as B2G) is an open-source operating system made for smartphones, tablet computers, smart TVs, and dongles designed by Mozilla and external contributors. It is based on the rendering engine of the Firefox web browser, Gecko, and on the Linux kernel. It was first commercially released in 2014.
Firefox OS was designed to provide a complete, community-based alternative operating system, for running web applications directly or those installed from an application marketplace. The applications use open standards and approaches such as JavaScript and HTML5, a robust privilege model, and open web APIs that can communicate directly with hardware, e.g. cellphone hardware. As such, Mozilla with Firefox OS competed with commercially developed operating systems such as Apple's iOS, Google's Android, Microsoft's Windows Phone, BlackBerry's BlackBerry 10, Samsung's/Linux Foundation's Tizen, and Jolla's Sailfish OS.
In December 2015, Mozilla announced it would stop development of new Firefox OS smartphones and, in September 2016, announced the end of development. Successors to Firefox OS include the discontinued B2G OS and Acadine Technologies' never-released H5OS as well as KaiOS Technologies' KaiOS and Panasonic's My Home Screen for smart TVs.
Details
I was leading UX design efforts for this project, as well as UI animations, second LED screen animations and Visual design for certain features, adapting a touch-based OS to a non-touch based feature phone platform. The platform was designed to support US-based cellular carriers and mobile OEMs, and was targeting the US aging population.
