It's a great alternative to NoScript. I've waited for a remake of noscript, but in the early stage, noscript isn't useable.

uMatrix fullfill all the tasks, what i need to have on my browser, all websites are set suspicious and blocks all vulnerable elements.
But i would likely uMatrix to remember my trusted choices, especially some domains, like googlevideo.com, gstatic or Captcha services.
I don't want to re-enable those things over and over again on different sites.

The NoScript debacle brought me here. I use uMatrix for a couple of days now, and I have to say that it works perfectly. After a short time of figuring out how it works I like it even better than the "old" NoScript. A simply wonderful extension, not so hard to get used on, and.... the most important of them all: it works great!

I you ever got used to NoScript in the past, the learning curve of this extension is comparable, though it's totally different in usage. The execution of the scriptblocking is even better than NoScript (my opinion), because you see immediately in the matrix what has been blocked.

A big thumbs up for the developer Raymond Hill. Great work! Thanks to you it's easy to forget NoScript, and I really hope you'll be just as succesfull with uMatrix as NoScript used to be (no offence).

You want a NoScript replacement that does it all? Look no further, because it's here!

Great idea but terrible implementation, at least here on Android. The ui is simply a mess, and the configuration page doesn't even load each time.

Habe viele Jahre NoScript benutzt. Doch die neue Version für Firefox Quantum gefällt mir nicht (neues UI und zu viele Bugs). Auf der Suche nach einer Alternative bin ich auf uMatrix gestoßen.... und was soll ich sagen... installiert... ausgiebig getestet... Fazit: SEHR GUT !!! Sehr übersichtlich das Ganze. Bin bisher begeistert. Vielen Dank an den Autor und klare 5 Sterne von mir.

So glad I found this. For those looking for a replacement for NoScript, this works.

В отличии от изуродованного в фф57 NoScript, этот блокиратор лучший.

Отличное дополнение! но нужно настроить правила один раз для ваших сайтов т.к режет иногда аватарки, иногда функционал чтоб комментировать и другое. удобней чем noscript, нравится! )

Really indispensable fine-level control of individual requests for power users.

Elegant and powerful! The only drawback is the lack of documentation and/or interactive tutorial.

This is the best Firefox add-on ever!
In my opinion should be a must, a FF built-in.

I read that the author uses UBlock, rather than UMatrix. It is not my case, and would like to share my logic:
UBlock is a great add-on too. However, if you use a more friendly granulated firewall (UMatrix), you avoid most of the ads, trackers, scripts etc. Doesn't make sense to use a more generalist firewall (UBlock), and at the same time having to add lot of filtering hosts/lists that reduce browser performance. The main filter should be the firewall itself, rather than the hosts/lists.
UMatrix well configured will block most of the stuff, without adding hosts/lists, and increasing browser performance.

Some users say that UMatrix "is difficult to understand, to learn, to configure etc", but this is not true.
The problem is not the add-on, but the user! Users don't want to read, to learn, to understand, to configure etc... they just want to install & use. The point is that UMatrix-wiki doesn't take maximum more than 15 minutes to be read, and another maximum 15 minutes to learn how to use it. Considering that UMatrix will work like 3 or 4 different add-ons at the same time, I prefer UMatrix taking me 30 minutes, rather than 4 different add-ons taking me 60 minutes or killing the browser performance.
And those users complaining about UMatrix breaking this or that... seriously... or they don't know how to use it, or they want the impossible (a firewall that blocks everything without blocking nothing).

My dream and request are:
1) A simple "disable option" at the main-panel, without white-listing (it is very unpractical to do it trough FF add-on page).
2) A real-time cloud malware/antivirus/phishing/ransomware etc service option.
3) A blocking ads and trackers/tracking not by hosts/lists, but by encoded rules (like "BluHell", "Privacy Protector" etc).
4) Same UBlock dashboard options in UMatrix dashboard. Another possibility (and perhaps easier) might be making UBlock firewall more friendly granulated as UMatrix.
5) Incorporation of same special NoScript filters, increasing security capabilities in unlocked-firewall.
For this dreamed add-on... I will be more than happy to make a fat donation!

Thousand thanks to the author!

This could be so freaking good. But ... it can be a real pain in the ass! Why? Because sometimes just having uMatrix enabled in the Extensions page of Firefox will break some websites even though uMatrix is set to "Disabled for this scope."

This occurs mostly on login pages, and one has to go to the extension page and disable uMatrix to login to a site. This is across both Linux and Windows.

If there was a way to COMPLETELY disable uMatix from the toolbar... well that would be great.

Great replacement for NoScript, thumbs up!
