Very good

Отличная штука

i never asked for this extension to be installed on my browser

Feature Request: I would like the saved theme to switch automatically based on the system's appearance mode (dark mode or light mode).

J'aime bien

Very useful. It could do with a couple more advanced features, like an actual reference of all the properties that can be themed and actual integration with the store.

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

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

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

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