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=)

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
(here are two I found useful:

Just like it said it's a
Point & click to forbid/allow any class of requests made my your browser.

The more I use uMatrix, the more I realize how beautiful its idea and UX concept are.

I was originally too "afraid" this was complex to use - not that it would stop me, but I thought it was something more than I wanted to spend time with browser.
Luckily I tried it, and very quickly realized that for me it served exactly the same purpose as NoScript - only easier. The use of scopes is fantastic - used te be that in NoScript if you allowed a domain, it was allowed on all sites; now you can select to allow things on particular domain only with the Custom option, but it's still not as flexible. And on µMatrix I by default allow on active scope, current domain - only things I know I'll want on whatever site wants to use it I'll allow for *. In NoScript you could certainly learn such habit, but it's more cumbersome, so you only go for custom rules for domains you specifically are allowing as exception on the site you're on. And even then it's less flexible than µMatrix scopes.

The only negative thing I have to say is: no version for Fennec. That is the mobile versions of Firefox, android in my case. On android FireFox I'm still stuck using NoScript.
I would likely hate using this UI in Android Firefox, but that's because of how Mozilla designed their current add-on UI system and is no better with NoScript - so come on, write that android version. Maybe try inventing slightly different UI that better fits the portrait mode while at it ;)

And thanks. This is golden.

A very useful add-on. Thank you very much.

Just the fastest, most flexible, and human-readable ad-blocker--- XHR req. are websites referencing others, just so you know.
