Firefox 9 is now available for download, with some huge performance improvements. One of the features Firefox 9 has introduced, is the Type Inference, which basically improves the JavaScript performance. This new feature can speed up the browser’s JavaScript performance by up to 30%, and comes with better integration with OS X and lots of stability enhancements. Also, many other stability enhancements and bug fixes have been added to the new version. Firefox 9 is not yet available through the official update channel, but you can easily download it from official Mozilla website.

The new version of Firefox comes with support for font-stretch, improved text-overflow and overall standards support for HTML5. Moreover, Firefox 9 also fixes several other CSS stability issues. It also offers Mac OS X Lion users with the new two-finger swipe navigation, and improved theme integration.
