Why have you used a black background and white letters as the default. It is absolutely horrid. I can not change it back to white background and black letters. Where do I change it to.

You can change this pref on the about:config page from 3 to 2 to revert to the Firefox 94 behavior.

  • layout.css.prefers-color-scheme.content-override
    Dark (0), light (1), system (2) or browser (3)

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

See also this pref:

  • ui.systemUsesDarkTheme [0:light; 1:dark; 2:no-preference]
