WebKit engineers have also joined other browsers in their efforts to standardize storage partitioning by allowing partitioned and ephemeral third-party IndexedDB, enabling full third-party cookie blocking by default so that ITP can learn about cross-site trackers during private browsing, and explicitly exempted home screen web applications from the seven-day cap on all script-writeable storage introduced in March. The bounce tracking detection feature and other ITP tweaks are also incorporated into Catalina and Mojave, iOS 14, and iPadOS 14, according to a post on the WebKit blog. Part of a raft of tweaks to WebKit’s Intelligent Tracking Prevention (ITP) feature, the seven-day limit mirrors ITP’s expiry cap on cookies created through JavaScript, which CNAME cloaking can circumvent.
