NoLeaks от olku

The extension helps you control potential privacy leaks by auditing external content on every website you visit.

In the pop-up you see all outgoing connections to external resources. You may block some or all of them and prevent leakage of any data in the future. Next time when you visit the website, these blocks will be applied automatically.

Blocked websites are shared with other users to help make the Web great again in terms of GDPR and privacy.

The extension is free of charge and open-source, distributed under public MIT license on https://github.com/noleakseu/extension
