I must admit, I have not always been a huge fan of Firefox for Mac, but the plugins available for FF are just great. Firebug in particular is a awesome tool to debug the xhtml and css on sites like this one, and if you’ve been here before you may notice small changes here and there. I really went through the site, trying as much as possible to adhere to a pretty strict grid, but the glory of xhtml and css is it’s not the same thing for all users. Firebug really helped me cut down the time of tracking down lines of css by having a great split screen UI in the FF browser that very much resembles the split screen of Adobe’s Dreamweaver.

The icing on the cake is that in addition to viewing the code, you can alter the code and see a real-time version of what that alteration would look like. Mind=Blown.
