No question, this is the most important addon for who cares about data privacy.

Mein Nr. 1 Add-On aller Add-Ons!
Ich kann ganz gezielt, individuell Einzelne zulassen oder blockieren (falls es nicht eh schon vom Standard blockiert ist).
Diese Einstellungen sind pro Webseite speicherbar.
Dieses Add-On trägt den Namen Matrix völlig zurecht.
Einfach geil.

The best web firewall for browsers, a shame it's not developed anymore, but will use it until the end or until I can learn 2code.

It would be great to adapt it for computer park administration, it would avoid so much malware from the web that isn't filtered by routing/rev-proxy.

If you're an advanced user, this is the best and most important extension for the modern web.
Using the web without it is actually unbearable. Seriously.
Thank you Raymond Hill!

Very useful and well-designed add-on. I was really surprised how intuitive and powerful the graphical interface is. Must have.

the most helpful tool I've ever used, if I ever use a different browser it better have this on it. not very easy to use until you mess with it for a bit then it's repetitive but gets very easy to use and you can even block yt ads with this and block the anti ad blocker.

This is a fantastic extension. You'll learn a lot about the web when you poke around with it when you browse. ... but you can get much of the same with its "sibling" extension, uBlock Origin.

This add-on should be implemented in Firefox itself. Actually in all browsers.

Все работает отлично=)

One of the best extension ever

amazing!

That is a next level of privacy management for advanced users

All things running under your nose are presented in tabular form and you can forbid/allow them just by clicking on columns/rows/cells.

Also, block hyperlink auditing, Regularly cache cleaning, Lists Subscription, Custom Lists, Import/Export settings and more...

be sure to watch a tutorial on how to use it otherwise some commonly used websites like facebook and youtube will become crippled

idk wtf just happened but all all rules i had set on umatrix for months... are gone. I closed the browser, reopened the browser, and they're gone. The browser is up to date. The addon is also up to date. F**** i have no idea if i ever saved/exported those rulesets
