Rated 5 out of 5 stars

Can't live without this add-on! I've been using Web Developer for about 2 years now, and it's the most important add-on I have installed. I use it constantly for troubleshooting css, checking css and html layouts, etc. There are tons of features, but the most useful is the Style Information found under the CSS dropdown. It shows an outline of any area you rollover, and the CSS when you click on it. Web Developer has saved me countless hours and stress, I'm sure! Great big thanks to the developer, I really appreciate your work and always look forward to future releases.
