For its new mobile and desktop OSes, Apple is redesigning the Safari browser user interface to be more compact and allow for better organization of multiple open tabs, specifically with a new feature called Tab Groups.
Tab Groups aim to offer a new way to easily save and manage related tabs, such as those used when planning trips or shopping, or groups can be used to store the tabs you visit daily.
In addition, a new tab design on macOS puts your active tabs front and center, allowing you to see more of the page as you scroll. At the same time, the new tab bar takes on the color of the webpage and combines tabs, the tool bar, and the search field into a single compact appearance.
On iPad, the new tabs design and tab groups work just like on Mac, with instant syncing across devices. On iPhone, the new tab bar appears at the bottom under your thumb with a tap, and it's possible to swipe between them, or swipe up into a grid view.
Meanwhile new extensions for iPhone and iPad also add to the native functionality of Apple's web browser, with shared code with existing Safari Web Extensions to make it easier for developers to create new ones.
