ダークモードにするアドオンをいろいろ試しましたが、このアプリが圧倒的に一番いいです。
もうブラウザでは必須で入れてます。
最高のアドオンです。

It extremely slowes down browser. Tested on multiple devices

This saves my eyes.

Tried other Dark mode plugins till I found this one. Has worked on a verity of sites wear others have failed. Great Job Alexander Shutau.

This is awesome! It can make web backgrounds pure black while having all text with high contrast. It can select colors dynamically in a smart way. I am really impressed! 10*

I work a lot with Google Suite like GDrive, GMail, GMeet, and GChat -- and this is definitely an eye saver!!!

This is the best extension you can get, for every site that doesn't have dark mode this extension darkifies it without ruining the layout, it works really really well

A very useful add-on. Thank you very much.

Excellent !!
