It's a lazy Sunday, and I have nothing to do, so I'm thinking of downloading and installing HideAway.

As some of you might know, I'm a long-time user of MailWasher, but this is my very first venture into the world of VPNs.
Aside from being visible when online, my internet experience is generally problem free, so I'm really not sure how I stand to benefit from using a VPN. As I said, though, I really don't have anything to do today.

Question 1.
Does HideAway only affect the computer on which it's installed or all computers on a local (home) network? All the machines are running Win 7 Pro x64.
Question 2.
I saw that someone asked a question about the Waterfox browser. I use the PaleMoon and Basilisk browsers; does anyone know whether they work OK with HideAway?
Question 3.
https://www.hideway.eu/vpn_server/english/
Am I correct in my understanding that the above site has nothing to do with Firetrust Hideaway? I must confess that I find it weird that two products with the same name exist in the world of VPN.
It's also problematic when looking for tests or reviews, e.g. https://vpnbase.com/vpn-services/hideway-vpn-reviews/
Question 4.
I just came across this:

Thank you.
