Can anyone tell me how to return the Firefox landing page background to white? I thought it was in the preferences section, but I wasn't able to actually change the background, just look at a whole lot of pretty colours.

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.
