- Firefox 5 Now Available with 1,000 Small Improvements, Better Tab Closing (Windows/Mac/Linux/Android)
Mozilla has released Firefox 5, the first update for its new rapid-release three-month development cycle. Firefox 5's new features include support for CSS animations, do-not-track on Android, and faster canvas graphics. Perhaps our favorite Firefox 5 feature: You won't have to jump around so much with your mouse next time you start closing tabs. Firefox has adopted Chrome-like tab closing, in which tabs stay the same size while you're closing them.
