Boot to Gecko / Firefox OS is a Gecko based mobile OS. However, the open apps platform we're building lets you run an HTML5 app on, well, any HTML5 device including Chrome, IE9, etc. This mostly applies to the Marketplace in how it offers paid apps; we have a decentralized receipt format to let the paid app run on any platform. Unlike any other mobile player, Mozilla is truly making the web the platform. Our platform is not Firefox OS. That's just one device to support open web apps.
