With more and more websites reading the browser theme settings, and changing to Dark Mode automatically, I really think it's time we have an option to stop websites doing this. I like my dark theme in Firefox, however I don't like websites in Dark Mode. Surely I am not the only user who wants this feature, either as an option in settings, or in about:config

I am a huge advocate for privacy, and the main reason I use Firefox over Chrome. I and like so many others, sacrifice the superiority and convenience of the Chrome browser, so we can utilize the great features Firefox has. And it makes me feel a little better inside knowing I am tracked less. I do not want websites reading my theme settings or any other non essential browser data. please fix this.

Have you tried installing a dark theme from the Firefox Add-ons site (

These may give you a darker theme, but without darker page content.

Try to set ui.systemUsesDarkTheme = 0 (0:light; 1:dark; 2:no-preference) on the about:config page.

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
