NSC Blocker

The NSC response header defines how websites can communicate that their content isn't safe, for example when it contains adult content. The header is defined in an experimental specification and implemented on the client side with this add-on.

This extension implements blocking and statistics regarding the "NSC" header.
It gives you the opportunity to try out the new specification yourself and to analyze whether your own websites implements the specification correctly.

Please have a look at our website for more information.
