- Firefox now supports the HTML5 video “buffered” property;
- HTML5 video “autobuffer” has been replaced with “preload”;
- An experimental CSS extension: drawing arbitrary elements as backgrounds with -moz-element;
- Increase default disk cache size from 50M to 250M (bug);
- Faster access to some DOM properties (.id, .className, .style, …) (see bugs 584287 and 584293).
