Is firefox network protection good for me to use?

Since I own Norton Lifelock, should I still sign up for Firefox Private Network?

And yes, I have VPN on.

 

Yes, I own Norton 360 with Lifelock. Seems like it should be sufficient; nevertheless, I thought I would ask.

 

Um, are you running Norton 360 with built-in VPN?
Um, are you running Norton Secure VPN?
