I am a developer. How do I get my website subdomain to be included in Firefox's automatic URL color-distinction for domains in the address bar?
Firefox currently has a URL color formatting scheme which greys-out all parts of the URL in the address bar except for the top-level domain and the 2nd-level domain (with some exceptions).
I am building a website where my organization-specific domain is NOT located on the 2nd-level domain, but rather on the 3rd-level domain.
I plan to use the domain "obb.ll.land". The "ll.land" part is basically a domain that the Liberland Government operates and from which it sells 3rd-level domains to members of the public. Think of "ll.land" as a temporary ccTLD for Liberland. (ICANN requires countries to be on the ISO-3166 list—which Liberland is not yet on—in order to register an official Internet ccTLD.) Therefore, any domain that is formatted as "[SUBDOMAIN].ll.land" should be presumed to be the foundational domain for a given organization that uses it.
Therefore, when a client sees a Liberlandic website, the domain should have the 3rd-level domain included in the black-text portion of Firefox's URL color formatting scheme. Otherwise the scheme would be misleading about the true nature of the website involved. For example, the 3rd-level domain of "https://www.floating.ll.land/" should be included in the black-text portion. Same with the 3rd-level domain of "https://register.ll.land/". However, as of this writing, no ".ll.land" site has the appropriate URL coloration to my knowledge.
How can I solve this problem? Is there something which developers like me should add to our websites individually, or will Mozilla be responsible for handling this matter?
Thank you all in advance! :)
