Firefox lets you control that, at least since the latest Developer Edition (101b7). Under Settings, General, Language and Appearance, one can choose between the following:

- match the Firefox theme

- match the system theme

- force light

- force dark

Nice! This might get me to finally switch to Firefox on Windows, after using in on my Mac for a while :)

Thanks! This also works in Firefox 100.

thanks!

I just figured iut that I can enable dark mode for windows apps globaly (Srttings -> Personalisation -> Colour), thanks!

So change the website theme to light mode? I use dark mode, and am happy when websites are served in dark mode (and I think the majority are this way). I think you're likely in the minority, and the easy fix is just to switch the websites you use to light mode.

The trouble is that `prefers-color-scheme` is set at browser or system level. In order for a website to use a different colour-scheme, then they need to add functionality with Javascript in order to be able to load different styling at user request.

I wish there were some URL-based rules you could set in the browser settings (I expect there are addons to do this, haven't looked though!).

What if the website does not provide a toggle to control to control this? I wish there was a browser preference to control prefers-color-scheme (which it sounds like new FF does!).

I don't really care that I'm probably in the minority of users who think or care about this. It doesn't make how I feel any less valid.

Maybe this would lead you in the right direction: chrome://flags/#enable-force-dark

Though, maybe that only does the reverse of what you're looking for.

You can override it via e.g. stylus or maybe https://stackoverflow.com/a/59223868

are there better extensions for providing styles that apply to every website than stylus?
