Extension summary
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.
