LocalStorage needs to be exposed in every context except for sandboxes and NullPrincipals (data: URLs, for instance). But we need to keep data separate in some scenarios: private-browsing and trackers. In private-browsing, LocalStorage keeps data in memory, and it shares StorageEvents just with other origins in the same private-browsing environment. For Trackers, we expose a partitioned LocalStorage, which doesn't share data with other contexts, and it's just in memory. Partitioned localStorage is available only for trackers listed in the privacy.restrict3rdpartystorage.partitionedHosts pref. See nsContentUtils::IsURIInPrefList to know the syntax for the pref value.
