After months of testing, Firefox 3 (code name Gran Paradiso) is available for download from Mozilla. With its new Gekko 1.9 engine, the browser rocks, rendering pages faster and using few system resources. As with any new browser, some add-ons created for Firefox 2 may not work, but give them time. Also, Firefox 3 includes many security-related features baked right in, such as the best of breed antiphishing protection, making Firefox the most secure browser on the market today. If you haven't already tried Firefox, what are you waiting for? Firefox 3 remains our Editors' Choice over Microsoft Internet Explorer and Opera.
