Incroyable add-on, très facile à prendre en main.

The browser starts with the default theme, and it takes a while to reload the correct theme created by color.firefox.com

It would be nice to have an option to automatically change themes based on the time of day, but otherwise this is as comprehensive a Theme Customizer as I could hope for.

This is perfect

It works fine I like it. It helps to identify which profile is in use currently. 4 star because one of my preset define as a dark theme and many page understand this as a system theme is dark. It could be a great extra to set the dark and the day colors as well.

Good Tool. Would have rated it higher but,
1. Exported themes won't install, they have to be signed by mozilla (a long winded process) and
2. The page layout for the popup menu box example, hides the saved themes option, making it impossible to select/change themes without zooming the page right down.

That said, exported and signed theme did install and work well. not really for novices.

If devs can fix these issues, its a excellent tool.

Pas de version en français, du coup je suis perdu dans tous les réglages.
Par exemple les textes dans les marques pages sont devenus très clair (beaucoup trop), et je n'arrive pas à trouver comment le régler car tout est en anglais !
Encore une perte de temps...

Created XPI file cannot be installed, browser says it is broken. :-( Tried several times and always the same result. :-(
