Firefox for Mac OS X Lion supports two-finger swipe gestures so you can easily navigate between websites. Firefox for Mac has an enhanced look and feel that matches the Mac OS X Lion icon and application toolbar styles and makes it easier to browse the Web using multiple monitors.
Web developers will notice Firefox helps websites load much faster, especially sites that download large sets of data or use AJAX. Firefox supports chunking XHR requests, allowing websites to display content as it’s downloaded instead of waiting for the entire download to complete. For more details about the new developer capabilities in Firefox, check out the Firefox for Web developers page.
