I have two problems with Dark Reader. (1) When I change to a new tab or new content for a tab I typically get a bright white initial display before Dark Reader kicks in to style the new content, completely dazzling my dark-adapted eyes and obviating the point of the extension and (2) Critical content is often unreadable using Dark Reader. I'm guessing that the first problem is not easy to address given the self-imposed limitations of FF's new extension mechanism!

if you listen to me you should download it
