I just love it.

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.
