A beta release of Firefox 4 has just landed and it’s better and faster than ever before. How much faster could this web browser be, you might ask? According to some recent benchmarks, it’s twice as fast as the stock browser in SunSpider tests and three times faster on Kraken. Not only is this much quicker than previous releases, it features increased stability, less memory hogging, and improved readability. Much like its desktop counterpart, Firefox 4 Beta also supports nearly 100 add-ons to allow for truly personalized browsing experiences.
