What is uMatrix?

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.

uMatrix: A point-and-click matrix-based firewall, with many privacy-enhancing tools.

For advanced users.

CHANGE LOG: https://github.com/gorhill/uMatrix/releases

uMatrix put you in full control of where your browser is allowed to connect, what type of data it is allowed to download, and what it is allowed to execute. Nobody else decides for you: You choose. You are in full control of your privacy.

Out of the box, uMatrix works in relax block-all/allow-exceptionally mode, meaning web sites which require 3rd-party scripts are likely to be "broken". With two clicks, uMatrix can be set to work in allow-all/block-exceptionally mode, which generally will not break web sites. See https://github.com/gorhill/httpswitchboard/wiki/How-to-use-HTTP-Switchboard:-Two-opposing-views for more details on this topic.

See ALL the remote connections, failed or attempted, depending on whether they were blocked or allowed (you decide).
A single-click to whitelist/blacklist one or multiple classes of requests according to the destination and type of data (a blocked request will NEVER leave your browser).
Efficient blacklisting: cookies won't leave your browser, JavaScript won't execute, plugins won't play, tracking pixels won't download, etc.

Az ublock-origin után ez a második dolog, amit egyből telepítek az új böngészőmbe. Nagyon hasznos bővítmény, bár tény, hogy kell hozzá némi szakértelem.

Quite the absolutely best security addon for Chrome, or Edge. Nothing is better. A full in-browser firewall.
