Three examples demonstrating the use of the declarativeNetRequest API:
- dnr-block-only: One minimal example demonstrating the use of static
DNR rules to block requests.
- dnr-redirect-url: One minimal example demonstrating the use of static
DNR rules to redirect requests.
- dnr-dynamic-with-options: A generic example demonstrating how host
permissions can be requested and free forms to input DNR rules.
