Excellent tool for privacy and safety on the web.

While it takes some configuration to take advantage of it, it pays off by giving a high level of fine-grain control not usually offered in other blocker extensions.

A totally miraculous add-on - uMatrix changed my life. It took a bit of learning, but quickly allowed me to dispense with several other add-ons, while giving me total control over what gets crammed down my browser's throat by the bloated monstrosities that pass for 'web sites' these days. Works terrifically well with Waterfox 56 on both Windows and Linux. (Sadly, this is looking like it may be the last version of Firefox I'll ever upgrade to. A big Bronx cheer to Mozilla...)

One suggestion: how about the ability to save multiple profiles for a site? (Right-click on the site name to select.) Very often I have a more relaxed secondary setup for making comments or accessing extra features. (On this site, for example, I had to allow cookies and extra scripts in order to post this review).

Просто волшебное дополнение, отлично сочетается с uBlock Origin (https://addons.mozilla.org/ru/firefox/addon/ublock-origin).

Позволяет ускорить работу сайтов путём запрета подключения к десятку сторонних ресурсов при загрузке страницы. Всякие счётчики, виджеты, рекламные сети - всё можно заблокировать.

Дополнение требует постоянного внимания к себе так как часто ломает сайты, но все его плюсы перевешивают это. Устанавливать данный аддон желательно только если вы продвинутый пользователь.

Крутая штука без нее даже мобильный from не использую.

THE BEST security and privacy tool around.
Thank you Raymond!!!

Dla czego Firefox nie autoryzuje ubloka? bez tego dodatku nie ma sensu przeglądać strony internetowych

Awesome for controlling all aspects of what your browser does. It's also very astute for picking out (and stopping) third party activity.

Crucial addon for gaining control over your browsing security and privacy.
It would be 5 star if it had keyboard shortcuts.

supersizing to see how javascript works , especially if one is trouble shooting connections. Very informative. thanks.
