The latest Firefox 4 Beta is available to test the cool features and improvements in the next version of Firefox. As we continue to refine features and performance in Firefox 4 Beta, this release includes faster start-up time, bookmarking and makes complex animations smoother.

Firefox 4 Beta is built for the way people use the Web today, offering more control over the browsing experience. It introduces a fresh new look and features like App Tabs and Panorama to make it easier and more efficient to navigate the Web. Firefox 4 Beta also includes performance enhancements to make everything faster from start-up time to page-load speed and the performance of Web applications and games. Firefox Sync is integrated into the browser with Firefox 4 Beta, giving you access to your Awesome Bar history, bookmarks, open tabs and passwords across computers and smartphones.

Firefox 4 Beta also enables developers to create fun Web apps and websites. With full support for HTML5 features in Firefox 4 Beta, developers can create new ways for people to enjoy the Web. This includes WebM and HD video, 3D graphic rendering with WebGL, hardware acceleration and the Mozilla Audio API to help create visual experiences for sound. Director of Product Platform Management Chris Blizzard has a full overview of all developer tools in Firefox 4 Beta.

We continue to improve and polish Firefox 4 Beta to ensure we deliver an awesome experience to our 400 million users around the world. We couldn’t do this without the help of our beta testers and their feedback. Please continue to test Firefox 4 Beta on your favorite websites and report issues with anything from games, video and music to graphics and forms through the Feedback button on the browser. We want to hear how we can improve the features of Firefox 4 Beta and performance on specific sites.
