Firefox 3.0 web-browser has been released! The new browser has much slicker (imho) user-interface, feels faster/lighter and is just plain awesome!

For FireBug users (i.e. any web-developer and designer?) out there: you need to manually download a new major release version, 1.2.0b4. Automated update of 1.05 won’t work.

Don’t know about Windows machines, but on Macs you can rename the existing Firefox to Firefox2 under Applications, before installing Firefox3 and that way you can keep running both in parallel (though not at the same time). Once you upgrade the plug-ins, you can not use them in the Firefox 2, anymore and you will start getting warnings. It’s still useful for testing rendering of websites and making sure your HTML/CSS works in Firefox 2, though.
