how to stop white flash first of page loading

Question: Can config per site be exported somehow and imported later or maybe config is saved as part of adon sync? It would help a lot.

This is still the best Dark theme. Although I wished it was a faster rendering the page.

Very useful, big compatibility with many sites i have tested on it !

Makes pages take too long to load and looks worse than other addons

Thank you very much! Firefox(desktop and mobile) should have a dark theme by default changeable in a simple way. It is very annoying that bright white when you are in a low light room and on mobile phones is stressful for the battery too. Cannot possibly understand why they don't make a light — dark theme by default.

Best Dark Addon i could find, but there is 1 thing that i dislike, white flashes whenever i open or reload a page. Is there a way to make firefox default background black while keeping this addon?

Breaks the structure of sites every time you change mode
