Briefings

Apple released Safari 27.3 for iOS, iPadOS, and macOS, introducing vertical tabs on the left side of the screen and an adaptive dark mode feature. Users can switch between horizontal and vertical tab layouts, with vertical tabs using icons by default to save space. The adaptive dark mode allows users to try dark mode on websites that do not support it, with an option to opt out. The update was tested by a user who previously used OmniWeb's vertical tabs, noting the new feature is a welcome addition. The release date is November 3, 2026, and the update applies to all three platforms.

Key points

• Safari 27.3 introduces vertical tabs on the left side of the screen, available across iOS, iPadOS, and macOS, replacing the standard horizontal tab bar.
• Users can toggle between vertical and horizontal tab layouts, with vertical tabs using icons by default to save space and support both Topics and Tab Groups.

Context
