Firefox 4 has been leaked for Mac and PC a day before the company said it would be officially available. Mozilla promises the user interface in Firefox 4 is sleeker and easier to use, and it enables users to keep open tabs, bookmarks, history, and passwords in sync with other devices running a Firefox browser. Firefox 4 also has a new feature that allow you to drag and drop open tabs into groups that can be arranged and named. The leaked downloads aren’t available direct from Mozilla, so we suppose there’s still a chance the team could pull the launch date tomorrow and issue an RC2 release, but we doubt it. We won’t keep you waiting, though, so hit the jump for a link to download Firefox 4 for PC or Mac.
