I'm passionate about making HTML5 games, you can tell by looking at my various private projects with the 'games' keyword inside: Enclave Games, js13kGames, Gamedev.js Weekly, HTML5 Gamedev Starter. Then there's also Firefox OS - I've created some games for the platform and wrote a few articles. I've run through the whole process of preparing your game for the Firefox OS platform, testing the game on the actual device and pushing it to the Firefox Marketplace. So, why not write a book about it? It's just another side project, so I have no idea when it will be finished, if ever.
