I just found out that it does not work on
steampowered.com either. The entire website is still the original colours even though I told it to use "Apple Mint" I still see white background once I log in to
steampowered.com
Some pages it just does not work. These are the pages which was the reason for installing this extension over dark mode reader and auto dark mode in the browser. Butt if this extension won't work on those pages too, I am back to searching for a dark mode extension.
Also once I toggle off darkmode on a website, the extension also toggles dark mode off for itself which is rather annoying that I have to accept the extension being white mode too if I want the page itself to be exempt from dark mode.
