Mozilla volunteers have recently been flooded with online merchants and marketers' requests for their domains to be added to what's called a Public Suffix List (PSL).
https://publicsuffix.org/
Public Suffix List (PSL) is an initiative of the Mozilla community volunteers to maintain a list of top-level domains (TLDs) and domains that should be treated as one to prevent the mixing of cookies between distinct domains.
That is because cookies set at a domain level could be used to on all of its subdomains, even if the subdomains are not related to each other or owned by the same organization.

Although maintained by Mozilla's open-source community volunteers, the list is honored by various apps and projects and helps them distinguish between a separate TLD/suffix and a subdomain.

However, recent privacy enhancements brought forth by Apple have led to online marketers flooding Mozilla with requests for their domains to be added to the list after Facebook suggested this as a remedy for the newer privacy enhancements.
