Didn't work. Pages are still bright white after installing. Using Firefox on Linux Mint. Like the fact it is open-source, but what I really wanted was a simple and convenient switch to manually turn night mode on and off daily.

Update: I found another extension called Super Dark Mode that does exactly what I wanted. With it, you can toggle dark mode on/off at any time simply by clicking the extension's toolbar button.

Пока один сайт ломает, crazygames.ru

The only extension that works without performance issues <3

Adds a white sheen to otherwise black backgrounds. See first screenshot for example. Sort of defeats the purpose of the extension.

quite nice . works as advertised

Does not work.

Thanks. 非常实用!
