Wenn man sie richtig verwendet funktioniert die Matrix einwandfrei, super Schutz!

This is a somewhat advanced add-on for a beginner, but actually a great alternative for no-script. The gui is especially helpful to any new users.

I would recommend using this right along side uBlock. As a pair they block most of the junk on the web. These add-ons also give great info on exactly what is trying to connect to you.

~ The content of the "Assets" tab is duplicates of what uBlock uses as filters. When using both uBlock and uMatrix there's no point to use the same filters twice. It would be nice if the Assets were more filled with rulesets that can be used in uMatrix specifically.

OK I have had huge issues with uMatrix abritrarily blocking certain elements in some sites, even if I add all the exceptions or even turn off the filtering for the entire site. I have finally figured out what is going on. If anyone else encounters this, open the uMatrix Dashboard, find the option "Spoof HTTP referrer string of third-party requests" at the bottom of the main "Settings" tab, and uncheck it. So far, I have found that doing this has fixed all of the issues I had previously encountered.

UMatrix: Soweit ich das beurteilen kann ist die Funktionalität besser als bei NoScript. Es werden alle urls sauber gelistet (mehr als bei NoScript) und man kann sehr gezielt entscheiden, was man freigeben will. Dadurch können ganz gezielte, fein justierbare Freigaben erteilt werden. Mit * * script block Eintrag kann man dauerhaft alle Scripte blockieren und er kann viel mehr als nur Scripte blockieren! UMatrix ist das beste!!!
UMatrix hat doch deutlich MEHR Einstellungsmöglichkeiten! Die ganzen Spalten der Matrix einzeln verwalten, nicht nur Skripte, und das für jede Seite einzeln, geht aber auch global... Es gibt schwarze Listen, die man sich aussuchen kann... Alles das kann NoScript nicht.
Das beste Addon aller Zeiten!!!

UMatrix is awesome.

fascinante

best and easiest to use. cookie block/lock sets it apart from similar blockers.
the interface is similar to ublock but more easier and more accessible.
very easy to learn and has a gentle learning curve.

Hey, how about to sync settings (my Rules) via FireFox Sync?

Muy útil a la hora de bloquear los elementos que uno no quiere ver en una página web.

I wouldn't recommend this to people that have a difficult time with computers in general as it can break some websites, but if you're patient and know what you want to block, uMatrix is better than any other script-filter out there.

Profi tool for managing content.
Only thing I miss is selecting individual scripts on a domain for blocking...

Very useful as 3rd-party content blocker and script blocker.

Thank you for uMatrix.

Thanks for the addon.

Click to play on steroids. Paranoia has never been easier to enforce.

Am confronting yet another uMatrix popover that only displays a big orange caution sign, the URL uMatix has blocked and a CLOSE button. The rest of the page is white space.

A GitHub page looked promising -
How to get past "uMatrix has prevented the following page from loading" - -
https://github.com/gorhill/uMatrix/wiki/How-to-get-past-%22uMatrix-has-prevented-the-following-page-from-loading%22

Trouble is, unlike the VERY nifty new-for-1.1.14 feature Ray described in great detail at the bottom and that I've already used a number of times (it parses URL parameters and really does give the intended hyperlink so you skip over the ad garbage and go directly to the page wanted) the top screenshot and explanation is incorrect, at least for me.

For example, when I visit an AT&T site to rant, a Feedback tab appears on the right side. When clicked, uMatrix generates a popOVER window up stating - uMatrix has prevented the following page from loading: https://secure.opinionlab.com/ccc01/comment_card_d.asp

Unlike his screenshot, these popover pages lack the isolated uMatrix icon or a tab on the top bar of the window (though there's one inside the address input line that doesn't do much) that standard FF browser windows would have. It lacks all of the typical FF icons - back arrow, refresh, search. There's just a very wide address window and the 3-barred settings icon at the far right.

That big Caution sign might as well be a Dead End sign. I'm still unable to find a way to UNPREVENT (disable) the uMatrix block! Help??

Also, I must not understand this review page's GUI. The review/question I posed a month ago that the dev kindly answered with info that others might benefit from reading has disappeared, with no warning that I was overwriting it by posting this second question a month later. It was still visible just before I posted this one. Any ideas wot hoppened??

Meglio di NoScript, perché decidi per ogni sito cosa usa e cosa no
