Ragyogóan láthatóvá teszi, ki mindenkihez kapcsolódunk a háttérben, és részleteiben szabályozhatjuk, ki mihez férhet hozzá. Persze egy kis IT ismeret szükségeltetik hozzá.

was a good extension

It causes a lot of websites to stop working altogether

This was working great until I just updated Firefox to v 90.0.2 (64-bit). Now, if I have uMatrix enabled, none of my browser pages display. If I disable it, they do display.

Best addon!

Many thanks to the developer for continuing the support for this extension, I am using it in most of my browsers as I want to decide site by site what to permit and what to block (I couldn't find a way to do this with uBlock or NoScript, though I am or was using these as well.

It doesn't support Firefox on Android

UI is messy and colorblind-unfriendly. Breaks Google Translate functionality.

Thanks a lot for security fix. This addons is so great and easy to use ! Thank you ;)

Excellent add-on: it allows me to enable only what is needed to get a site working, without permitting cookies and add-ins from the dozens of 3d-party sites whose content is often incorporated into modern websites. Yesterday (2021-JUL-25) it broke Firefox's Internet access completely, but updating to v1.4.4 fixed the problem.

It works perfectly!

uMatrix unexpectedly came back from the dead! Its dev has luckily changed his mind, hurray!
