On Monday, Mozilla released the latest beta update for Firefox. The “Beta 2” version of the Web browser includes a number of great new features that Firefox users envied in other browsers, including private browsing mode, improved rendering, and a faster JavaScript engine.

However, Mac users are in for a treat. Firefox 3.1 now has built-in support for the MacBook’s Multi-Touch trackpad. In fact, Firefox will support even more gestures than Safari, Apple's default browser, does. The multi-finger gestures (three fingers for a swipe and two fingers for a pinch or twist) include the following:

- Swipe Left: Go back in history (hold Cmd to open the last page in a new tab)
- Swipe Right: Go forward in history
- Swipe Up: Go to the top of the page
- Swipe Down: Go to the end of the page
- Pinch Together: Zoom out
- Pinch Apart: Zoom in
- Twist Right: Next tab
- Twist Left: Previous tab

As of now, there's no known release date for the final version of Firefox 3.1
