Cannot enable anything other than a dark screen
For me, running 101.0 on Windows 11, Firefox disregards the selected theme and shows web pages in black no matter what I do (except for these support pages, oddly). Sometimes it renders as black text on a black background, making it impossible to use. My windows theme is "Light", my Firefox theme is "Light". I CAN select ALWAYS to override every web page with a light background and dark text, but obviously that interferes with the design of most web pages. This problem has persisted for months. I have read the suggestions about changing UI settings in about:config and none of them work. As much as I love Firefox and Mozilla, there are many web pages rendered unusable by this problem, and I am about ready to throw in the towel and start using Chrome.

You can check the website appearance setting.
- Settings -> General -> Language and Appearance -> Website Appearance
None of these suggestions work other than as already stated. I have set both the Windows and the Firefox themes to "light" and Firefox still displays every page as dark.
You can change this pref on the about:config page from 3 to 2 to revert to the Firefox 94 behavior regarding to prefer dark or light background for webpages. You can use 0 (dark) or 1 (light) to set a specific state.
- about:config => layout.css.prefers-color-scheme.content-override [dark:0, light:1, system:2, 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.
I have tried that since it's suggested in several other posts, but it doesn't work.
