The two comments stating Dark Reader are correct. Not specific to Medium but can be turned on and off per site. Great extension but sometimes causes slowdowns while loading pages on my old hardware debian laptop with little hard drive space left. Rock solid on my phone and higher specced machines.
Dark reader for FF plus Twilight for red light screen overlay on android makes for great low light/dark reading.
What extension is causing that auto dark theme? Specific to medium?
Most likely Dark Reader.
