Google Chrome for Mac
Google Chrome is a browser that combines a minimal design with sophisticated technology to make the Web faster, safer, and easier.
Use one box for everything--type in the address bar and get suggestions for both search and Web pages. Thumbnails of your top sites let you access your favorite pages instantly with lightning speed from any new tab. Desktop shortcuts allow you to launch your favorite Web apps straight from your desktop. The developer's build tests new features before they're pushed to the beta build, and so it should only be used by those who are willing to risk browsing data loss.
