Open up about:config and go to layout.css.prefers-color-scheme.content-override and set it to one of the following:

0 => Force a Dark background

1 => Force a Light background

2 => Follow the System theme (default in Firefox 94)

3 => Follow the Browser toolbar theme (default in Firefox 95+)

    You light mode monster. Dark mode for life.

      Unless you have astigmatism, dark mode is a nightmare to read when your vision is not good.

        I have astigmatism and disagree wholeheartedly. Light mode is like staring into the sun.

          Just looks like this for me

          Just need a well lit room for light mode and at least the white of the background bleeds into black text making it grey rather than the blurry mess of white on black.

            I have astigmatism too and for me it looks just as bad when inverted, a blurry mess of black on white.

            To me, what makes one a better choice vs the other has more to do with my environmental lighting.

            • If I’m on a place with a lot of light, the screen being black makes it have reflections so I prefer black on white in those cases.
            • If I’m in a dark place, the bright screen makes the screen itself the primary source of light which is not good for my eyesight, it can make my eyes feel like burning/tired after a while.

        did you try making the text bigger and using red text instead of white?

        red, being the slowest color visible for human eyes, is physically the easiest

          I think you mean either longest wavelength or lowest frequency… or maybe lower energy?

      I’m not a edgy programmer

      I just want something that is readable. Is that to much to ask?

      What I really want is the resist fingerprinting theme. Don’t ask me why but it is the best for some reason.

    I think this is also in Settings under Language and Appearance, Website appearance, unless this is a stricter setting that ensures it works as desired.

      Readability

      The Firefox light UI sucks but I don’t want website turning into black unreadable nonsense.

    You can also use Dark Reader in a reverse way by forcing everything into a light theme, or sepia if that makes reading better for you.

      I don’t want pure light mode. I just want the defaults for each website.

    You don’t need about:config for this.

    This is the same setting you can configure in the preferences under “Website appearance”… if you change that you’ll see the about:config setting changes too.

      I just want text to be readable. Not everyone is hanging out in a basement.
