This is the best of all dark mode add-ons. Very intelligent, preserves the aesthetics of the website and adjusts itself according to the website. Other addons just disable everything and the images are not visible and ruin text selection background, whereas this addon adapts itself very nicely.

Best dark mode plugin YET

You/we should distinguish visited links from non-visited (different color).
Please, check google search and darken white ribbon when scrolling. Google translate has a big white annoying ribbon... But all and all, great extension.

this is the best you can amaging

One of the best dark mode extensions available for firefox. Much better than any other dark mode extension as it doesn't just invert the colors of webpages, it maintains the aesthetics of the webpage as well. 10/10 would recommend.
