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

It's the easiest way to make your own Firefox theme. Unfortunately, exported themes are always corrupted, so you can't share them easily.

i really like this add-on however after updating firefox, this add-on is no longer working. please fix this

Decent styling utility. Unfortunately, it doesn't work as expected with vertical tabs. The background image/pattern option doesn't apply to it as it would with horizontal tabs.

Super, sauf quand on veut importer un ancien thème dedans pour l'éditer : c'est tout simplement impossible, il faut se retaper l'ensemble des choix un par un.

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