After a bit of trial and error, I found this easy to use. My eyes are so sensitive to bright screens so this add on really helps!

SUPERB ! Once you find the add-on, and tweak it a little, it works great. My recommendations to the developer: 1) improve key-word search to find it (see "Dark Reader"). 2) adjust default colors - see "material.io": #121212 and #C3C3C3. 3) Consider extending the color with "opaqueness" to a full RGB-A model. Thanks again for this add-on :)

It's more easy/friendly interface and ways more customization compared to DarkReader.

Funktioniert auf Anhieb genau wie es sollte! Danke, macht das Arbeiten gleich viel angenehmer

Quiet fast in doing its jobs which is surprising by it self. Web Look issues are subjectives so far.

Customizable and so reliable! Great work from the dev, thank you

Indispensable... C'est bien d'avoir un thème sombre mais beaucoup de page restent avec un fond blanc ce qui rend la nuit la navigation fatigante pour les yeux... c'est exactement ce que je cherchais. simple et fonctionnel.

It doesn't distinguish well between, background and foreground or images. Images should change, nor the foreground nor letters unless, they're too dark and can't be seen.
Doesn't Breaks Wikipedia pages' numbers, it was my fault for using the wrong San Serif Font: TwemojiMozilla.ttf
