For some website, such as [https://sspai.com/ 少数派] ， support both the dark and the normal mode. My Windows system setting is dark mode, so in Edge, this website deliver a dark theme, but in Firefox, it always display a normal mode----white backgroud and black text, I have tried reinstall Firefox, try other edtion of Firefox such as the Nightly, but none of them make help. What should I do? Thanks!
