I’ve heard a lot of good things about the Web Developer extension for Firefox but damn is it ever cool! The fact that you can visually display where CSS tags or blocks or divs or classes or whatever start and end is amazing. Want to see what colour and type that font is? Just turn on the elements info, hover your mouse over it and it will show you. That is just sweet! I realize some of my friends are going to go “Huh? Web Developer? CSS What? Block Who?” but someone who knows just how rough it can be to decipher someone else’s website’s style – especially if you’re trying to steal something 😉 – will appreciate this.
