When users do interact with these items, they'll be shown an alert warning them that they may then be tracked.
There will also be new security measures to prevent digital fingerprinting, or the use of things like installed fonts and plug-ins to help track users across the internet even with privacy settings active. Websites will be given a stripped down, simplified system configuration so every user's Mac looks like every other user's Mac.
Safari will also gain new password organizing features that automatically creates and stores passwords and flags reused passwords between sites so they can be changed.
The new Safari will be released this fall for iOS and macOS.
