+    Brave allows users to select additional adblock filters by visiting brave://adblock. We recommend that you do not use this feature and stick to the default settings provided by the Brave Shield to not stand out from other braves users and to not increase your attack surface. If there is a vulnerability in the Shield, third party filters can provide malicious rules to exploit it.
