The latest version of Firefox is now available with over 1,000 improvements and performance enhancements, including new CSS Animations and Do Not Track for Mobile. We're also releasing the Firefox Add-on SDK and Builder that make it easier for Web developers to build add-ons using HTML, JavaScript and CSS.

Celebrate the Firefox 5 launch by making your own paper firefox (or make more for your very own skulk of foxes). Thanks to the Mozilla Indonesia community, there are two firefox paper toys to choose from.

With the new rapid release schedule, the next versions of Firefox will be here soon and a number of new developer tools are coming in those releases. Learn more about Highlighter, Style Inspector, Command Line and more, and find out how to get involved with the tools team.
