My must-have extension on Linux/Windows. It has options (with keyboard shortcuts) to toggle darkening of each site or to toggle the whole extension globally. Also, it can auto-toggle globally depending on: 1) system theme, 2) latitude/longitude, 3) time.

Это дополнение решает проблему отсутствия темной темы на сайтах, отсталые хозяева которых видимо не подозревают, что не всем удобно читать чёрный текст на белых страницах. Теперь мой монитор по ночам не выполнят роль прожектора! При этом сайты остаются читаемыми.

This is the single most amazing browser extension of all time. The extension doesn't work on firefox store pages(sadly), otherwise it is awesome.

And I read the recent negative comments on the chrome store and that is intolerable. I don't know about them, but you guys are always most welcome here on the FOSS side of the sea.

The very first thing I saw after installing was the word ”pay”...
The warmest ”welcome” to uninstall. Immedately!

text is light grey on white background for overdrive books

Love the option to keep the filter on permanently while dynamically toggling light/dark theme based on system dark/light setting. This is different from default behavior. Light mode becomes less glaring this way, a light grey instead of pure white. What a pleasure it is to read this way!

Gen Settings:
√ Enable by default
√ Detect Dark Theme

Automation Settings:
Use system color scheme
Toggle Dark/Light

I tested many extensions for dark interfaces and this is the best: reliable, adaptable, highly, configurable but mostly automatic. I love it!
Thanks to the developers! <3
