"Right at this moment, big changes have or are about to occur in three well-known browsers: Internet Explorer is finally being updated, with version 7 in its third beta and almost ready to roll out the door; Firefox is also ripening an upgrade beta for its Version 2.0 - it's in beta 1; and finally Opera, which has a devoted but smaller following, has recently come out with Version 9.0. So, three new browsers in the same year, after no action for a half decade. How do they stack up?"
