Firefox dark mode made a couple sites unusable but Dark Reader seems to have solved that with a nice contrast setting without losing images or darker items on a page.

在黑暗里看屏幕的必需品

Freaking awesome! Best thing ever made! THANKS DARK READER

i tried other dark modes, i keep coming back to this one

makes the browser unbearably slow on every single site it's on. sucks bc it's the only dark mode for android
