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

Отличное приложение! Радует, что есть возможность для каждого сайта настроить свой вариант: Invert либо Stylesheet Processor. Но есть одно просьба: сделайте, пожалуйста, подложку иконки приложения прозрачной, либо сделайте белую обводку по квадратному краю, а то, на отличной от тёмной темы Firefox, смотрится не комильфо.
