As you may have heard, Internet explorer 8 Beta in now available for download. This release is designed for developers and designers to get a head start on making things work with IE8. I would not recommend downloading this beta release because many users have reported the browser crashing repeatedly after installation.
Some of the new features of IE8 include:
-Automatic Crash Recovery
-Improved Phishing Filter
Here is the link to the Readiness Toolkit which includes the Beta download.
Firefox 3 beta 3 is also available for download.
