Rated 5 out of 5 stars

Completely priceless for web development! This is the ultimate tool for tweaking every last detail of your page to get rid of all those little annoyances that degrade the viewing quality of your site, like unnecessary or missing padding and margins, weird inheritance, etc. If only there such a tool on for IE6!

This review is for a previous version of the add-on (1.4.3).
