The best VPN around. Fast, simple to set-up and cheap. I use it on a regular basis on both Firefox and desktop (Windows, Linux).
Highly reccomended

been using NORD VPN for 3 years and no issues, now that ISP's are being requested to block VPN's we will have to get more creative. So far so good

doesn't have a free version.
upd:
gotta have plain and simple description telling that you don't have a free version, otherwise it's just time wastin' for users.

Этот VPN Premium? Удоляю..

Nordvpn is the best vpn proxy extension ever. I like it.

Funktioniert zuverlässig, Geschwdigkeit ebenfalls ausreichend. Einzelne Anwendungen/Websites werden ungewollt blockiert. Alle konnten mit Split tunneling gangbar gemacht werden.
Insgesamt sehr zu empfehlen.

This extension on Mac (maybe Windows also) is leaking your home DNS. Test it for yourself. Nord VPN recommends you use https://www.dnsleaktest.com/ this website will tell you all is fine. But if you use https://ipleak.net/ or https://www.expressvpn.com/dns-leak-test it will reveal your home DNS and who your broadband provider is. Don't take my word, check this for yourself. It's a massive security flaw.

no issues
