iOS 27.3 Adds Vertical Tabs and Adaptive Dark Mode to Safari

Key Points:

• Apple is introducing major Safari updates in iOS 27.3, iPadOS 27.3, and macOS Golden Gate 27.3, including a new Vertical Tabs layout available across iPhone, iPad, and Mac, which places tabs on the left side with options to show icons or website titles.
• The Vertical Tabs feature integrates with Topics and Tab Groups for better organization, supporting pinning, quick swapping, and automatic tab sorting via Apple Intelligence.
• Safari will gain Adaptive Dark Mode for websites without native dark mode, dynamically adjusting backgrounds, text contrast, and graphics to improve readability, with options to enable it per site or globally.
• New Siri AI actions will allow users to manage tabs, windows, and web history via voice commands, and upcoming Siri enhancements will enable understanding and querying of webpage content across multiple tabs.
• These Safari features are currently in developer beta and will be publicly released in December with iOS 27.3, iPadOS 27.3, and macOS Golden Gate 27.3, requiring Apple Intelligence-capable devices for Siri functionalities.
