Ну просто очень полезное дополнение, этакий фаервол для интернет страниц, у меня работает в тандеме с uBlock Origin, окончательно удаляет с сайта рекламу, лишние куки, запросы, перенаправления и другую гадость. Страницы становятся девственно чистыми, рекомендую.

once you get a hang of umatrix, it is by far the best security related addon. its much easier to manage your preferred settings than the others. id give it 6 stars if we can use simple text files for im/export databases, and of course saving them too...

uMatrix is now my #1 most essential add-on for Firefox. It lets me know at a glance what Web sites are trying to cram down my throat, and it lets me selectively allow exactly the minimum to get the functionality I need.

Just ONE small request, which would make this add-on PERFECT: I'd love to see a way of saving multiple configurations for a single site. Very often I develop a lower-security setting to get at specific content - but I need to re-enter it from memory every time I visit the site looking for that particular content.

Otherwise, bravo! I'll never willingly use the Web without uMatrix.

Wer sich etwas mit dem Addon beschäftigt und ein bisschen Arbeit nicht scheut, wird begeistert sein. Kenne nichts besseres.

Amazing job!. A must have. It is my favorite now.

Amazing extension. Seeing how much garbage that some websites try to load in the background is eye-opening. Figuring out how to unbreak some websites is actually kinda fun, even for an amateur like me. This extension gives you so much control over what you want to allow or block. Definitely recommended for anyone who's even slightly tech-savvy.

This is the absolute hands down best extension ever made, unless the developers are not to be trusted which I have no reason to believe that they aren't. This app is not for the inpatient, uneducated, stupid and idiotic fools. This app is for anyone willing to put forth the effort to learn what each site does and potentially can do. It takes time to learn and that is going to be frustrating for most users. Get over it because it is worth it!!!

Advanced Script, Pixel and AdBlock. Sometimes even useable against antiadblock. The only thing i'd like to have would be an selective blocker (dont block all scripts but instead select them).
