Browser Permission API Errors — Notification, Geolocation & Camera Denied

Overview

Fix browser permission errors for notifications, geolocation, camera, microphone, and clipboard access including permanently denied permissions and reset procedures.

Key Details

• Modern browsers require explicit permission for sensitive APIs: notifications, location, camera, mic, clipboard
• Once denied, some permissions are permanently blocked until the user resets them manually
• HTTPS is required for most permission-gated APIs (camera, mic, geolocation)
• Permissions API (navigator.permissions.query) can check permission state before requesting
• Cross-origin iframes may be blocked from requesting permissions by Permissions Policy header

Common Causes

• User previously denied the permission request (now permanently blocked)
• Page served over HTTP (not HTTPS) — permission APIs require secure context
• Permissions Policy (formerly Feature-Policy) header blocking the API in iframes
• Browser settings globally blocking a specific permission type
• Extension blocking permission prompts
