Manage block lists and whitelists

Choose a source

Import from a URL, upload a file, paste rules, or maintain domains manually. Supported input includes domain-per-line lists, hosts files, and common DNS-oriented Adblock rules. A stored example.com also matches subdomains.

Set where it applies

1. Open Block Lists or Whitelists and create a named list.
2. Choose source and format; import the entries.
3. Apply globally or assign the list to policy targets.
4. Set enabled state, schedule, and a refresh interval for URL sources.
5. Use Policy Tester to confirm a matching domain and an expected exception.

Refresh without discarding working data

URL sources refresh independently. Unchanged sources can skip parsing and writes; failed downloads or unusable empty sources retain the last known-good list. Open the list editor to inspect entries, assignments, and refresh status.
