Yeah, a lot of our engineering effort is going into performance right now, rather than new features. But here are some of the HTML and CSS features in Firefox 4: - HTML5 parser (SVG/MathML in HTML, new semantic elements) - HTML5 forms (only partly implemented so far) - Web Sockets - CSS3 transitions - CSS3 calc() - IndexedDB (schemaless client-side database) - WebM (VP8) codec for HTML5 video - SVG backgrounds and images in CSS and HTML - ECMAScript 5 features in JavaScript
