Safari Updates in iOS 27.3: Vertical Tabs, Adaptive Dark Mode, and Siri AI Intents

Safari Updates in iOS 27.3: Vertical Tabs, Adaptive Dark Mode, and Siri AI Intents

Apple has introduced significant updates to Safari in the latest iOS 27.3, iPadOS 27.3, and macOS Golden Gate 27.3 betas:

  • Vertical Tabs: A new UI layout option for improved tab management, compatible with Topics and Tab Groups.
  • Adaptive Dark Mode: A browser-level rendering engine that applies dark mode styles to websites lacking native dark mode support. Developers can opt-out using specific CSS or HTML tags.
  • Siri AI Integration: New intents allowing Siri to programmatically manage tabs, windows, and history. Future updates will enable Siri to parse full webpage content, including non-active tabs, for cross-site information retrieval.

These features are available in the current developer beta and are expected to launch in December.
