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.

Really like it, but it slows down firefox way too much

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

few days my internet became so slow.
I couldn't understand what make my browsing so slow... until I have disabled the Dark Reader :(
really sad cause it was great idea

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!

Any chance to make it compatible with firefox 52 ESR? Thanks

Top Addon !!

Awesome on the eyes. Pretty speedy too!

This is an awesome addon, very useful. However, I would love to see its performance improved. It clearly slows done the loading of a page, even simple ones.

Ставилось для чтения переводов вебстраниц на translate.google.com. Панель переводчика конвертирует, но фрейм с текстом перевода остается в оригинальных цветах. Также, в отличие от штатного Firefox Reader View не позволяет задавать гарнитуру, кегль, межстрочный интервал и кернинг. Наконец, сепию считаю необходимым заменить или дополнить красным фильтром, для чтения перед сном. Firefox 66.0a1 x64, Windows 10.

Thank you for bringing joy back to my eyes. Seriously, this work you have done is greatly appreciated. Best add on I have ever found.

Is is really a very useful addon, the only problem with it is that it slows down page loading. It is painfully so sometimes. Works better under chrome, i hope the developer will cope with this problem under firefox, too.

It's not perfect, sometimes I have to disable it on a page to fix errors and sutch. But it works fine for most sites and I don't like browsing without it.
