It's support was ended 2 years ago but it still works perfectly and feels complete enough that I don't feel like it necessary to move on to something else. I have yet to find a plugin with an interface as good as uMatrix has.

Nutze es seit über einem Jahr, ist super nützlich und nach einer Eingewöhnungsphase auch nutzerfreundlich zu bedienen.

The best Add-on! ᚢ ᚢ ᚢ

Sadly not actively developed, but still works amazing, I find it better than any other privacy plugin, or even than combination of them. Due to how easy it is to customize/adjust on per page basis, no deep menus or anything, click, whitelist some domains, done.

nice script and content blocker.
easy to adjust and unblock if needed. great work. Thanks

Amazing - a must have
