About Filters
Firebog maintains a collection of blocklists intended for use with Pi-hole to reduce ads, trackers, and malicious content. Lists are grouped by purpose, such as suspicious domains, advertising, and tracking and telemetry, with markers showing which lists are least likely to interfere with browsing and which are not recommended.
The site also offers URL-only and CSV versions for automated updates and a tool to keep blocklist sources in sync. Lists hosted at v.firebog.net allow basic aggregated statistics to be viewed via CloudFlare, and users are asked to report false positives to the original list maintainers.
