Rated 5 out of 5 stars
The web developer toolbar is absolutely essential for me. It helped me writing my diploma thesis, which was about accessibility and WCAG1 and 2. It saves a lot of time in my everyday work as a web developer. And finally it was very helpful the last ten years when I was teaching web design. I really miss it when I open a browser where it is not available.This review is for a previous version of the add-on (1.1.9).
