It works on most sites; some have to be tweaked. In general, it provides a coherent experience for those who are fond of dark themes.

Works and looks better than all the other dark web browsing extensions I've tried. Plus it has a lot of customization.

Great add-on, works perfectly, thank you!

Works great with no issues.

Really good, love tthe sepia mode to make stuff brownish low contrast.

Karanlık teması olmayan siteleri koyu hale çeviriyor. Şu an da bu uzantının daha iyi alternatifi yok. Tarayıcıların kendi sundukları koyu modlar halen deneme aşamasındalar.

Recien instalada, fresca, sutil, bien hecha. Un artista su creador, joder !Un puto genio¡

Works much better than other extensions. There are some others that broke the websites and delay to load until the theme is changed. This ones work perfectly, I even didn't notice the difference between this extension and youtube black theme.

It is the only one I know that achieves a dark background on the web pages, and it works without me doing anything.
Thank you very much.
I tried "Stylus" but it's too complicated for me.
I hope that in the future Firefox will allow add-ons to do their job without requiring "access your data for all websites".
For now, I am trusting it because "Recommended" by Firefox.

Tried hundreds of modes, this one is cleanest and most easy on eyes

SUPER! La seule extension que j'ai trouvé qui permette de régler la luminosité indépendamment du thème (jour/nuit). Plus le mode sépia qui permet de "casser" la lumière bleue de l'écran, parfait quand il se fait l'heure de dormir. En plus de Redshift qui tourne sur ma Lubuntu c'est parfait. Merci!
