Safari
Safari is getting some much-needed love with a new tab organization feature that shows the website icon in the tab and provides a preview window, so you can see the contents of each tab without clicking it.
Apple also improved its extensions giving you control over how they are being used. You can set an extension, so it’s enabled for a single day, a specific website, or every website. Other improvements include integrated translation and a customizable start page with background image support.
Privacy comes to the forefront with a new Privacy button added to the toolbar. Clicking on this button provides insight into how sites are tracking you and using your data. It also shows which tracking features have been blocked.
