Works as expected. Can be intimidating at first, but once you start configuring it you'll get comfortable and gradually have to configure it less.

The matrix makes it easy to find what to unblock.

Awesome add-on to improve your privacy and security

this extension gives you total control. The best script blocking FireFox add on available. Intuitive, clever and precise. A must have for browsing the web.

Give you the ultimate control over web scripts, with an INCREDIBLY intuitive and logical user interface (once you know how it works). Occasionally a page needs a hard-refresh to load with changed permissions, but I've had no other problems with it at all.

Best way to have granular control over entire domains. Kudos, Raymond.

Excelente mejora notablemente la seguridad del equipo.

Dodatek dla bardziej zaawansowanych użytkowników, nie ma co tu dawać niższej oceny za to, że po zainstalowaniu dodatek psuje strony, bo właśnie od tego on jest, po to by działał praktycznie jak zapora systemu która jest nieskonfigurowana od pierwszego momentu, domyślnie wszystko jest blokowane i wszystko musisz stopniowo, metodą prób i błędów dopuszczać. Polecam dodatek dla osób które są zaawansowane, dla tych mniej zaawansowanych polecam inny dodatek tego samego autora pod tytułem uBlock Origin.

После трёх месяцев эксплуатации :
Спасибо за великолепную замену почившему NoScript-у.
5/5 от меня. Продолжайте в том же духе.

Umatrix is a great and powerful add-on! It's not very easy to understand how it works at the beginning but it's worth the effort to learn how to use it in my opinion.

soft 3rd-party default-deny + * * cookie block + some per scope switches + all host files activated = i'm happy. no need for any additional privacy/adblock extension and fastest surf experience ever (in comparison with other content blockers). thx 4 your work & continuous development. new users: wiki : https://github.com/gorhill/uMatrix/wiki . the matrix is absolutely intuitive, far away from complicated. take your time, don't waste your time.

Easy to figure out what to turn on to get missing parts of a page to appear
