Martin de Keijzer gave a presentation on Firefox OS (Firefox/Boot to Gecko) at SmartDevCon in Poland. He discussed the core components of Firefox OS including Gonk (the Linux kernel), Gecko (the web rendering engine), and Gaia (the user interface). He explained how to build and run Firefox OS on different devices and emulators. Finally, he covered how to develop web apps for Firefox OS using a manifest file and ways for developers to contribute such as providing feedback, submitting pull requests on GitHub, and uploading apps to the Mozilla Marketplace.
