Browser Kernel

Manage the browser engines available to your apps. Open it from ⋮ → Browser Kernel.

Features

• Current WebView info — inspect the system WebView version on this device.
• Embedded engine — download, manage, and delete the optional GeckoView (Firefox) runtime, used for ECH / SNI encryption. Shows download size and progress; the heavy native artifacts are fetched on first use.
• Change WebView provider — switch the system WebView provider (with developer-options steps guidance).
• Engine descriptions — reference info for Chrome, Edge, Brave, Firefox, and Via.

Notes

• Per-app engine selection happens in the Build APK dialog; this screen manages the engines themselves.
• GeckoView is required for ECH.
