Firefox is Web Design

I recently went through all of Firefox's web development add-ons to see if there was anything of use to me in there. I ended up clicking on most everything like I do. One of things I clicked on was the Web Developer Toolbar and I must admit that it is bloody awesome. I haven't even really used it yet I've been too busy checking out all the options it has. There's a button for pretty much everything. I've been doing up my boss's site which involved me making up my own CSS for it so that I know better what it is that I'm tweaking. The way I was doing it was guessing how many divs and sections I might need and where they would go and then through trial and error changing the sizes so that I end up with the stuff in the same place. This took me ages. And just as I finished, with everything looking good I decided to have a look of the Web Dev Toolbar to see what it did. I clicked a button and it showed me on the original exactly where every div was, what size they were and any other attributes and properties that I wanted to know about. If I had known about this earlier I would of had my CSS made up in a matter of minutes and been able to get on with the process of redesigning the site the way I want it. Definitely a recommendation for anyone who's into web desing especially beginners because I know how frustrating it can be to get your head round the concept of divs being the site layout when they're just written out in a text file.
