I know I’m a bit late to the game, but some of you may not know that Mozilla Firefox 1.5, was released last week. If you are still using Internet Explorer on your Windows machine, you should install and start using Firefox because its more secure, faster, and extendable. This Introduction to Firefox is a great starter’s guide for making the switch form IE.
If your a web developer or designer, you should be interested in what’s new in the browser. Simon Willison has an overview of new CSS tags, and other feature, that Firefox supports.
