- About "_Use KarmaAPI to detect stealthy Cloudflare domains_" settings option
This add-on does not make internet connection by default.
This option is disabled by default.
If you enable above option, the add-on will lookup only domain name (e.g. `https://www.mozilla.org/blog/ -> send only "mozilla.org"`) with [Karma API](../service/karma_api.md) service.
And if the domain is listed in our Cloudflare Domain list, the add-on will block/redirect/notify you based on your preferences.
