If you haven't installed or updated to Firefox 3, WHERE HAVE YOU BEEN?!
You can download it from the official website at http://www.mozilla.com/en-US/firefox/. It's available in 46 different languages and compatible with 3 Operating Systems (OS): Windows, Mac and Linux. Talk about going global.
If you're currently using Firefox 2, I would assume your greatest worry would be whether Firefox 3 is hard to navigate, and whether your add-ons are compatible.
You can relax. Firefox 3 boats of the same interface, save for the Awesome Navigation Bar. Don't worry, if you don't like what you see, you can change or edit it back to the setting as per Firefox 2 style.
As for your add-ons, the numerous Firefox 3 betas released enabled code developers to start editing the compatibility, and if the update manager informs you that the add-on is incompatible, just be patient. The odds are that Firefox developers are vetting through them.
