iOS 27.3 Adds Vertical Tabs, Adaptive Dark Mode to Safari

Apple is adding vertical tabs and an Adaptive Dark Mode to Safari with iOS 27.3, iPadOS 27.3 and macOS Golden Gate 27.3. The December updates will also expand Siri's browser controls, including organizing tabs and clearing site-specific history, with a later feature allowing Siri to understand and answer questions about content across multiple open webpages. MacRumors reports: Vertical Tabs are located on the left side of the display and use icons by default to save space, but there is an option to make the tab bar wider to show website titles as well. Vertical Tabs work with both Topics and Tab Groups to keep things organized. Topics are created when automatic Apple Intelligence tab sorting is turned on in iOS 27. Pinning tabs by dragging, quickly swapping between Tab Groups, and other features also continue to work.
