I use a custom Firefox theme which is great - but it doesn't work well with Windows system dark mode. With this extension, you can define a Firefox theme to be used when Windows system dark mode is enabled / disabled.

"Change themes based on the system theme" option does not really work (no auto-switch, just the background sometimes). As well as Manually set time

sep2024 upd: seems to work now

Doesn't work. Firefox 129 & Sonoma 14.6

Very good. I only miss a direct way to change the extension settings, for instance, clicking on its extension's icon.

"Change themes based on the system theme" option doesn't work at first

.....

Очень классное расширение

schon

Funciona como esperado e dá para escolher entre qualquer tema já instalado no FF para ambos os modos. Ótimo!

Nice idea, but the option to change theme based on system doesn't work for me. To be more accurate, it works inconsistently: sometimes it changes it, sometimes it doesn't.

Absolutely wonderful addon! I had no idea this was possible. Firefox is horrible at day/night switching and this addon does it PERFECTLY. Thank you so much.

This extension has become an integral part of my browser
