Although Microsoft and Mozilla released new versions of their browsers (Internet Explorer 9 and Firefox 4, respectively), its safe to say that neither company is resting on its laurels.

Although Firefox 5 beta is coming only in May (with the final version scheduled for June release), you can try pre-beta release right now – just head over to this page.

And you can also try out IE10 Platform Preview 1.
