serviceWorkers :
[NOTE] indexedDB and serviceWorkers are not available in Private Browsing Mode
[NOTE] Blocking cookies also blocks websites access to: localStorage (incl. sessionStorage),
indexedDB, sharedWorker, and serviceWorker (and therefore service worker cache and notifications)
If you set a site exception for cookies (either "Allow" or "Allow for Session") then they become
accessible to websites except shared/service workers where the cookie setting must be "Allow"
[NOTE] As Thunderbird lacks of ETP Strict Mode support at the moment, we still enable FPI (4000),
have to deal with persistent storage here and enable state partitioning of service workers (2790)
