Makes YouTube default to its Dark Theme by initialising the relevant cookie
< 脚本Default YouTube to Dark Theme的反馈
location.reload();
In my case, on the embedded pages, the player restarts endlessly.

Thanks for the handy script that uses Youtube's built-in dark theme.
I want to suggest a small improvement by adding a page refresh so that the dark theme is applied immediately:
if(!c || !c.match("^PREF=|; ?PREF=")) {
document.cookie = "PREF=f6=400;domain=youtube.com";
// Reload the page so that the changes take effect immediately
location.reload();
}
