Literally the BEST security addon for Firefox after NoScript, with almost the same level of power and control.

The very first and the most awesome addon I add everywhere I can.

No question, this is the most important addon for who cares about data privacy.

Mein Nr. 1 Add-On aller Add-Ons!
Ich kann ganz gezielt, individuell Einzelne zulassen oder blockieren (falls es nicht eh schon vom Standard blockiert ist).
Diese Einstellungen sind pro Webseite speicherbar.
Dieses Add-On trägt den Namen Matrix völlig zurecht.
Einfach geil.

The best web firewall for browsers, a shame it's not developed anymore, but will use it until the end or until I can learn 2code.

It would be great to adapt it for computer park administration, it would avoid so much malware from the web that isn't filtered by routing/rev-proxy.

If you're an advanced user, this is the best and most important extension for the modern web.
Using the web without it is actually unbearable. Seriously.
Thank you Raymond Hill!
