or... just lower your monitor brightness so you don't feel like you need dark mode, which is actually worse in every way than just using the correct monitor brightness.
Sorry I didn't mean any negatively towards you there. I just remember what the site was like before it hit my blocklist. It was before chatgpt got big but everything I read on there was scraped info from other sites and full of errors
Firefox with the extension "Dark Reader" is great. There are some websites I have to disable it, but it's rare. I also recommend uBlock Origin.
Edit: I see someone already recommended dark reader. But it really is a must have extension. It knows if your system theme is set to light or dark and matches it automatically.
making it a per-profile settings does not exclude making it available per-device or per-visit. it's not especially difficult to store a flag in localStorage or a cookie. hell, you can even use CSS to detect OS dark mode preference settings and have it change automatically with no user input at all.
I just want them to follow system default for guest user(s).
they probably require an account because they have a system set up in a way where it's mostly a server-side app and ui settings are only stored on the server
This makes more sense for signed in user(s).
No dark mode unless you register, is what I consider to be a asshole design choice.
