How to Configure Per-Website Settings and Permissions in Safari on macOS

Modern web browsing demands flexibility: while high-volume news publications and blogs benefit from aggressive ad blocking and automatic Reader View formatting, internal business intranets, banking portals, and video streaming services frequently require custom zoom scalings, unrestricted media auto-play, or camera and microphone access. Applying universal browser-wide policies often leads to broken website functionality or constant manual toggling. Safari on macOS includes a dedicated per-website management engine that allows users to establish granular, persistent behavioral rules for individual domains without compromising global privacy standards.

Accessing Domain-Specific Settings Directly from the Address Bar

The fastest way to configure custom settings for the domain currently loaded in your active tab is via the Smart Search field menu:

1. Navigate to the target website in Safari on your Mac.
2. Right-click (or hold Control and click) inside the Smart Search field (the URL address bar).
3. From the contextual menu, select Settings for This Website….
4. A popover HUD window will descend directly below the address bar, presenting all active permissions and content display rules assigned to that domain.

Configuring Reading, Zoom, and Content Blocking Preferences

Within the popover interface, you can customise visual rendering preferences that apply automatically whenever you return to this website in the future:

• Use Reader when available: Check this option to instruct Safari to strip away advertisements, navigation headers, sidebar widgets, and comment sections automatically on every article published by this domain, rendering text immediately in clean Reader Mode.
• Enable content blockers: If a specific website breaks or prevents login because third-party content blockers filter necessary interactive scripts, uncheck this box to disable ad-blocking extensions selectively for this domain while leaving protection enabled across the rest of the web.
• Page Zoom: Click the zoom percentage dropdown to scale text and media up or down (from 50% to 300%). Safari will remember this scale factor exclusively for this domain, preventing small-font sites from straining your eyes.

Managing Media Auto-Play and Hardware Privileges

The lower half of the per-website settings dialogue manages audio emissions and hardware sensor access:

1. Auto-Play: Select from three media handling policies:
   • Allow All Auto-Play: Permits video and audio streams to commence playback immediately without user interaction (ideal for video conferencing web apps and streaming platforms).
   • Stop Media with Audio: Allows silent video playback (such as muted background loops) but blocks any media that emits sound until clicked manually.
   • Never Auto-Play: Prevents all embedded video players from starting automatically regardless of audio state.
2. Hardware Sensor Access: Configure persistent permission states for Camera, Microphone, Location, and Screen Sharing:
   • Ask: Safari prompts you every time the site requests access.
   • Allow: Grants permanent access without issuing security dialogs.
   • Deny: Silently blocks the site from detecting or requesting the sensor.
3. Pop-up Windows: Choose whether Safari should block or allow modal pop-up windows specifically on this domain.

Auditing and Resetting All Configured Per-Website Rules

Over time, as you establish custom exceptions across dozens of web destinations, auditing all active rules from a unified control panel ensures outdated permissions do not persist:

1. Open Safari on your Mac, click Safari in the top menu bar, and select Settings (or press Cmd + ,).
2. Click on the Websites tab at the top of the preferences pane.
3. The left-hand sidebar lists every configurable category: Reader, Page Zoom, Auto-Play, Content Blockers, Pop-up Windows, Camera, Microphone, and Location.
4. Clicking any category displays a central table listing all websites with custom rules, alongside a selector for currently open tabs.
5. To remove an obsolete domain rule and restore Safari’s global default behavior, highlight the domain and click the Remove button at the bottom of the table.
