This option allows you to adjust all subdomains to inherit your preferences from the main domain.

 

Example - Tumblr.com

  • If the Subdomains option is OFF
    • Tumblr.com - will be converted, by default, to Dark mode. However, subdomain.tumblr.com will still be in Normal mode.
  • If the Subdomains option is ON
    • Both Tumblr.com and subdomain.tumblr.com will be automatically converted to dark mode.
