Mozilla has revealed some previews of its new Firefox 4 browser which they claim will be 'super duper fast'. Most notable are the IU changes that are inspired by the minimalist Google Chrome browser approach, support for HTML 5, CSS3, Multi Touch support and hardware acceleration via Direct 2D.

It will be interesting to see who wins out between firefox 4 and IE 9 - they both look very similar on paper, but it will be the user experience that will win the competition, not the browser that has more acronyms to its feature list.
