The name for the concept comes from the name of the HTTP-SwitchBoard extension (predecessor to uMatrix). It's skeuomorphic. The extensions which have a switchboard like interface enable the user to block requests based on the request's domain name, the primary frame's domain-name, and also the type of request. In contrast, extensions like NoScript have a global switch. If I allow scripts from DontBeEvil.com, they are enabled on all domains. They don't prevent XSS attacks, for example. If there's a better name for this concept, please do suggest one.
