I can explain this one ...
Sorbet Leopard uses a custom derivative of the
March 2021 MVPS Hosts and
foxPEP 2.2 Bloat Trimming Engine ad / tracking / fingerprinting domain blocklists as a base for the system-wide ad blocking feature (enabled by default), and is an instrumental reason as to why Internet browsing in Sorbet is so fast in comparison to regular Leopard.
Because
www.facebook.com and
connect.facebook.net are widely known and notorious tracking servers that span all over the Web (which they make use of to build a shadow profile of you for marketing purposes among other more malicious uses), it was included in the foxPEP Bloat Trimming Engine in order to better protect the user's privacy and integrity of identity. Naturally, this inclusion then carried over to Sorbet when the two were merged.
Its effects can be disabled entirely by navigating to
Applications > Utility Scripts > System > System-wide Ad Blocking > Disable System-wide Ad Blocking. Restart any open browsers, and then try again - although please be advised that overall browsing performance will in most cases be greatly reduced as a result.
I hope that was helpful.
