I keep pointing this out every time dark mode comes up, so don't take it personally: embedded browsers (like the ones in RSS readers) cannot use extensions, and only native dark mode support in the site itself works there. It is _extremely_ annoying to get a white flash while reading news in the night time, and I really don't get why HN doesn't have a pair of CSS lines that would fix it for everyone.

The latest version of Qt WebEngine supports both userscripts and extensions.

But embedded browsers could always inject their own userscript for dark mode, so I don't really see the problem.

You don't use iOS, do you?

Are you using iOS, or is iOS using you?

Just tried it and it makes the vote buttons disappear (mobile Safari).

Seems to work fine for me on firefox and chromium:
