I tried adding style to userChrome.css

@-moz-document url-prefix(about:blank) { 

   * {
       background: black !important;
   }

}

and https://support.mozilla.org/en-US/questions/1106886 but both did not work. Dark mode extension works after loading a page but not before loading page in new tab.

I found a solution by chance. I'm using Linux so I changed GTK theme to Arc-Dark this changed pre-loading screen color. I think other themes with dark mode work too.
