This extension has been outmoded as NF now uses firewall level tracking and blocking which renders this extension obsolete, so the negative reviews surrounding it being "easily turned off" lead to nowhere. HOWEVER I am against the practices of NF as a whole as I believe it is spyware and infringes on the privacy of certain individuals as well as hinders natural development of teenagers and young adults in the post-internet age.

Slows down computer a lot, just testing products. Please delete this product, I'm tired of getting emails and reviews saying how bad this product is. Any person can disable this extension without parent supervision.

This is a joke protection: any body can disable it!
