Very useful extension for someone like me that wanted to make Themes for my Firefox browser.

another MASTERPIECE, from the creator of this browser. thanks mozilla

It is Great I love it. I have used it for years and I am very happy with it.

I like this thing.

Perfect. I created my first theme using this tool and submitted the XPI file as a Firefox theme for the whole world ^^

It's an amazing and simple way to create your own theme that matches your desktop. However, I would like it if they added more visual/text descriptions of each thing especially under "advanced". Those who are not FF users for long wouldn't know the names of each element. And documentation talks about code and Jsons

Couldn't get it to work because i was using another extension, autocolor. I'm liking this better

Excellent, lightweight plus customizable and easy to use. Keep up the good work. thanks

Very nice! easy to customize :) so cute :)
