I know there are several options for forcing dark mode on various sites such as userContent.css
in Firefox and the Dark Reader extension. However, some browsers such as Brave and Bromite have a built-in version of this feature.
It would be great for Orion to have this built-in "dark mode" for any site so that we can be sure extensions aren't spying on us or doing other nefarious things with our data since they require expanded access to work.
