Firefox is the gold standard of alternatives to the still-dominant Internet Explorer. Firefox 3.6 is full-featured, lightning fast, and secure. Its killer selection of add-ons remains strong, with built-in support for the next generation of themes, called Personas, plus the latest update makes version 3.6 about 20 percent faster than version 3.5. However, competition is strong and it can no longer be said that Firefox is the fastest browser available.
Unlike Firefox 3.5, which was more about keeping the browser current rather than blazing new trails, Firefox 3.6 is once again on the warpath. Upgrading is highly recommended.
