Hi, i am on linux an Firefox 115.0.2. Every supported website appeared in dark mode because of my preferences in the firefox settings respectively about:config layout.css.prefers-color-scheme.content-override is set to 2 and my system mode is dark. (0 and 3 changes nothing) Since some time this settings does not work anymore. The only thing i have changed is: about:config - privacy.trackingprotection.enabled set to true So now all the websites appeared in dark mode now appear in light mode. Chrome shows all these websites in dark mode. (But of course thats no option :-)) An Example: reddit.com: before: dark, now: light mode, Chrome dark mode. So please help! regards, awilli

Chosen solution

Make sure that privacy.resistFingerprinting is set to false in about:config if you want sites to detect dark mode preference.

Edit: setting back to about:config - privacy.trackingprotection.enabled set to false did not help. (laptop not restarted)
