“We’ve made big improvements to kinetic panning and added the ability to scroll iframes. A lot of work has been done to make our theme more robust, taking advantage of things like media queries to support various devices, orientations, and platforms which you’ll see more of in the next Windows Mobile release. Overall, this beta is a major improvement to previous Fennec betas” said Stuart Parmenter, Mozilla’s director of mobile engineering.

Full details of all changes, plus download links can be found in the release notes.
