на некоторых сайтах экран становится полностью черным

not working properly

Poder cambiar la intensidad del brillo de la pagina web con un solo click en el sol es excelente.

Extension either doesn't darken a page, or will darken it and remove all text and images. Pretty useless extension. Don't download.

On LibreWolf this addon blacks out all colours on G Calendar and MS Office online, which I badly need for my work.

blacken the whole page including text

Man this is LEGENDARY

Doesn't seem to work with glassdoor website. I wanted a dark theme for that website while I browse for jobs

Does only allow to exclude websites, while I want to use it on one specific website

No settings. Dark Mode is either on globally for every website or off. Would probably use it, if I could set it for individual websites and not globally. It also overrides websites that already have a dark mode...
