Block or allow requests

Block matching requests

1. Create a block profile.
2. Add conditions for the requests to stop.
3. Enable the profile and reproduce the request.
4. Confirm in Developer Tools that the request was blocked.

Exempt traffic from other profiles

Create an allow profile when matching traffic should bypass lower-priority blocking, redirect, upgrade, or header-modification rules from Headerly.

1. Create an allow profile.
2. Add narrow conditions for the exception.
3. Give it a priority at least as high as the rules it must override.
4. Verify the request and all expected headers.

Use allowAllRequests only when you need an exception for a complete frame hierarchy. See Allow, Allow all requests, and priority behavior.
