uMatrix: A Point-and-Click Matrix-Based Firewall for Your Browser

uMatrix is a matrix-based firewall Chrome extension designed to put users in control of their browser's activities. It enables users to decide where their browser connects, what type of data is downloaded, and what is allowed to execute, offering unparalleled privacy control. Out of the box, uMatrix blocks all 3rd-party scripts, which can be adjusted according to user’s preferences. Its filtering engine uses precedence logic to evaluate what is blocked or allowed. Additionally, it provides basic protection against trackers and malware sites.

User reviews

Chrome keeps trying to remove this from my browser, but doesn't understand how necessary it is to security. Chromium needs to add this as core functionality before ripping away extensions that improve security from browsers.

Отличное расширение. Жаль, но сегодня, google уведомил что оно больше работать не будет...
