Proposed fix: [browser-use] 'Navigation to <url> blocked by security policy' for file://, localhost/IP or redirected URLs when allowed_domains / block_ip_addresses is set
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Add explicit patterns for what you need (e.g. 'http://localhost:*' style full-URL patterns or 'file:///*'), avoid block_ip_addresses for local dev, and include redirect targets.
Option: Add explicit patterns for what you need (e.g. 'http://localhost:*' style full-URL patterns or 'file:///*'), avoid block_ip_addresses for local dev, and include redirect targets. [evidence: official_recommended_action]
Applies when: Agent navigates to local files, IP hosts, or pages redirecting off-allowlist
Steps:
1. Inspect the logged blocked URL
2. Add an allowed pattern (full URL patterns with '://' use prefix/glob matching)
3. Disable block_ip_addresses for localhost testing
4. Include SSO/redirect domains
Expected: The error no longer appears.
