@waymondrang Hi! I don't know if it's thanks to my comment (probably not) but there was an update recently and now it works even better than before! Thanks!

Before the new docs update DocsAfterDark changed the color only of docs itself rather than the page as well, but since the update it's just kind of broken and it works only on 2/3rds of the site and still doesn't change the page's color. I'm using it on OperaGX but it works perfectly fine on Firefox even after the update
