A few years ago, after losing a lot of hair trying to develop a website for my local organization, scanning through cascading style sheets that were hundreds of lines long and keeping elaborate documents to track image sizes and colors, I finally stumbled across the Firefox Web Developer add-on. It’s a simple tool that many of you probably already use, but if you’re new to web development or you’re just trying to tweak your site’s theme, you’ll want to take a look at it. I promise that it will save you hours of frustration.
If the video above was just enough to peak your interest, but you would like to know more, visit a few of the sites listed below that have more elaborate and detailed explanations of what the add-on can do. Happy developing!
