This is a (yet another) brilliant add-on by Gorhill. Raymond however decided to focus on uBlock and not update uMatrix anymore (see last update date). As with all good, useful software, uMatrix was forked to nuMatrix. Both uMartix and nuMatrix are fine and work very well keeping "the rest of the world" in line.

Amazing extension, allows me maximum control of what is shown on the screen. I can be as harsh or as lenient as I want on a per-site basis. Took a bit of tinkering to learn what can and can't be turned off without breaking the site but after I learnt that It became a very useful too!

Great tool to have fine-grained control of what a website is allowed to do!
However, it is more for the advanced user that has a rough understanding what is necessary, and what is not.

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
