Mozilla experts are now receiving the various request from the online merchants and marketers that was requested for the domains that would be added to the list named as Public Suffix List (PSL)
Public Suffix List is associated with Mozilla organization while maintaining the top-level domains and the domains that should be worked as to prevent the mixing of other cookies between the different domains.
However, the cookies set at a domain level could be used as all the subdomains, even these domains are not related to each other or owned by a similar organization.
Apart from that, Mozilla is an open-source community that volunteers the list of several applications and projects that are assisted by them and able to separate between TLD, subdomain, and suffix. The recent privacy enhancement is driven by Apple which initiates this flood to Mozilla having requests for the domains that would be added to the list of Facebook that suggest this as the substitute and the remedy of new privacy enhancements.

Mozilla PSL Volunteers Swamped With Requests
As Facebook stated the listing domains in PSL it would be a great thing to be a part of the domain verification process, the online stores are rushed with the demands, and the maintainers are using the old PST and requesting while adding the domains to them.
Meanwhile, several issues were founded by GitHub that are linked with PSL maintainers, and these are also raising the concerns and rejecting the request. Whereas, it affects the result of the Apple ATT framework that online advertise the things for those who are still accessing Facebook’s pixel-based tracking mechanism and also checking the conversions while blocking the cookies.

This entire issue will reduce the efficacy of targeting the ads and performing work measurement in some cases that are mainly from eCommerce platforms that permits the attackers while allowing the subdomains of every storefront.
For example; booksforcheap.shopnow.com, midnightcookies.shopnow.com, and many others.
However, a Facebook engineer that explained about the PCM which couldn’t work and not be supported by Facebook and time is very effective.
While adding to the PSL the etsy.com will ensure the subdomains and are worked as separate properties and permits the several store owners to collect the metrics those includes the Private Click Measurement what was specific for the stores.
However, the Mozilla spokesperson state that this Public Suffix list was started multiple years ago and it is not a standalone domains list that suffixes the co.uk or tokyo.jp. The maintainers are also becoming volunteers from the Web community and Mozilla welcomes all the volunteers working.
Numerous no of peoples are depends on this list of the dataset that was mistakenly added the domain to the list and the best thing is that the organizations support the projects while adding the appropriate request to the list.
PST is the group of volunteers that are helping and maintaining the wide user’s resources and these are not dependent or swamped by the thundering herd of requests that may or may not is appropriated.
