i am sorry, i do not want to discourage the programmer, but i doubt the whole idea... something so simple , like setting colors in a software should be integrated offline in the program itself. while genious makers like decentraleyes make it possible to load needed code from local instead of dozens online sources, we now ping the cloud to set a color ? why should i visit hxxx://color.firefox.url to do this ?
Mozilla! What are you doing, you are about to crush your reputation entirely... i thought you care for security, but now we shout to the web, user x has clicked this button.. and he browses in pink, and his ip is ...... ! yay... well done....

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 ^^
