Very interesting and useful. It just takes a little learning.

The best Webpage design toolkit you could possibly ask for (or even imagine) for Firefox. Highly recommended to any Web developer. Thanks, devs!

It is an perfect plugIn for Development! But if there were a 'back' (Str, Z) key-Bind, it were much better! <3

Works excellent. Lightweight tool for front-end devs.

👏 Perfect for front-end development!
