The Winner: Firefox 3

Though the latest version of Firefox retains much of it's predecessor's basic looks, it's usability has improved. For instance, as you type a Web address into the bar, Firefox 3 searches your bookmarks and browsing history for matchings based on how often and how recently you visited a given site. To see the most important Firefox 3 upgrade, open either the history or the bookmarks window. Both of them now live in an SQL database that displays them together.
