Apple’s iOS 27.3, iPadOS 27.3 and macOS 27.3 betas add vertical tabs and Adaptive Dark Mode to Safari, alongside new Siri actions for managing tabs. The reports say the updates are available for developer testing, with a wider release expected in December.

Safari’s new Vertical Tabs option places tabs along the left side of the display; users can show icons or resize the bar to show website titles.
Adaptive Dark Mode can create a darker version of a site without its own dark mode, and can be enabled across sites or individually.
Siri can act on tabs, including sorting, moving and closing them; broader webpage-content awareness is described as a future feature.
