I hate that folks recommend random extensions. Browsers should include style/css editors (with the ability to save and reload styles later) for accessibility. Since we don't have that, uBlock Origin does a lot of heavy lifting, and can add a dark mode to HN and other sites.

I'd share my ruleset, however, I am missing one. Before I switched PCs (motherboard caught fire) I had one that made everything dark mode, didn't dim the text, and buttons/text inputs/other inputs were also properly inverted. I had to make it myself because googling Hacker News dark mode always led to the same broken themes. I forgot to back it up. Adding dark mode doesn't need a bunch of extensions, and while I'm sure the "stylus" extension is probably useful (I haven't used it, sounds like a CSS override extension), UBO does CSS and JS.

Just my thoughts. Don't mind me.

Indeed, I just figured I'd share the full setup. IIRC, Stylus was derived from "Stylish", which was a hugely popular CSS override extension that became spyware around 2016 and was taken down in 2018, and now Stylus (and others of course) fill the gap. It would be very nice to have this integrated into the browser, I agree.

Opera had this in 2003, but sadly none of the major browsers copied it.

I still miss Omniweb, a browser with user defined stylesheets, per site settings, and workspaces… so many good things. Free browsers killed it off.
