I don't want a dark theme and have tried numerous times to change it to a light theme. Within a min. Firefox returns to a default dark theme without me touching anything. Is there something that I am missing or is this newer browser in need of repair? This is getting old, I have used Firefox for years, never had a problem with kind of issue before. Thanks

You can select a theme that has dark text on the tabs (toolbars) if you currently use a theme with light text to prevent Firefox from using a dark background for webpages.

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.
