<h2>Introduction to Firefox OS</h2>
<p>Firefox OS (also referred to by its codename "Boot to Gecko" or "B2G") is Mozilla's open source mobile operating system based on Linux and Mozilla's Gecko technology. Firefox OS is a mobile operating system that's free from proprietary technology while still a powerful platform that provides application developers an opportunity to create excellent products. In addition, it's flexible and capable enough to make the end user happy.</p>

<p>For Web developers, the most important part to understand is that the entire user interface is a Web app, one that is capable of displaying and launching other Web apps. Any modifications you make to the user interface and any applications you create to run on Firefox OS are Web pages, albeit with enhanced access to the mobile device's hardware and services.</p>
