            Bug ID: 187494
           Summary: MiniBrowser lacks entitlements to add extensions
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Macintosh
                OS: macOS 10.13
            Status: NEW
          Severity: Minor
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: opendarwin at lapcatsoftware.com

Steps to Reproduce:
1. Build WebKit on macOS 10.13
2. Debug MiniBrowser
3. Open "Debug" menu
4. Select "Show Extensions Manager"
5. Click the + button

This fails because of sandboxing. To fix, you just need to add the User Selected File sandbox entitlement to the MiniBrowser target App Sandbox Capabilities:
