Been using this extension for some years on multiple web browsers. Some sites (or domains) can be troublesome, but this generally works really well, helping to alleviate eye strain.

One of the greatest addons!

I like this add-on very much, very well done and very effective. The adjustment setting options are superb, I have tried other extensions but they were either too dark or yellow this is a good fit for me.

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.
