=== HTML5 support and documentation ===
=== HTML support and documentation ===
The better we document and explain Firefox's HTML5 support, the more developers learn about it and put it to use in real world web apps, the more feedback we get on Firefox's HTML5 implementation and know what to improve and iterate on, etc. A key goal here is to encourage an ever stronger feedback loop that improves the state of the art of HTML5 Web App development in general, and in particular with building increasingly higher fidelity HTML5+CSS3 Web Apps with Firefox as a development platform.
