Firefox now has a dark background on a "simple" html page without css styling (see screenshot #1). You may reproduce this issue by browsing to a local page like http://localhost:8080 with something like a 404-page (see screenshot #2)

That far - dark mode is cool, isn't it? Yep, it would be. If the text would not be black, on a dark background.

Happens to me without any plugins, or any userChrome etc. (Screenshot was taken with plugins on, but disabling them (and restarting) had no effect)

Workarounds discovered: - set `layout.css.prefers-color-scheme.content-override` to 1 (This changes nearly everything to white, which is not what I want.

- Setting theme to the builtin white/light works, but: 

    - View Source has white text on white background (see screenshot #3)
    - Everything is in light mode, and thats simply not what I want

What I would expect: - Viewing a page without shitty modifications - Viewing a white page (suprise suprise) white
