Does not work anymore. Although I have a paid account I just can't use it anymore. It says it can't connect to their servers and it does not show any country list. I can however connect through the desktop app without problems.
Support Bot at support.nord-help.net does not have a option for firefox addon.

Needs improvement. Favorite countries could be added.

Sometimes the complete list of countries does not show up, you have to logout and login again to see the whole list but somehow countries from recent connections work. So, a simple favorites list which is kept locally will do a lot more than recent connections.

edt: Once more, I propose adding favorite countries/servers to prevent deleting cache, cookies or logging in-out everytime that error occurs.

this thing does not connect, keep getting the same failed to connect error...

3rd class, so laggy , not good for video.

NOT recommended.. NordVPN extension 2.21 is becoming what many of us want to avoid on the internet. During login it digs around inside browser and throws a captcha page. It is broken in browsers modified to limit this sort of negative behaviour. From a privacy and security company the behaviour of this extension is surprising and disappointing. Earlier version 2.17 behaves in expected and acceptable manner... it connects proxy and nothing more.

EDIT: Nonsense response from the developer. Classic deflect and distract to draw attention away from real issues. People need to understand this extension is heading in the direction of data miners and spyware.

Can never search for a country, only quick connect works, help please?

Recaptcha for a privacy addon .. why not add in google analytics?!

I like the idea of Nordvpn as a solution but the recent update on the addon has included a recaptha, just to make the experience of having to login at every occasion even more sucky!!.. why the addon cannot remember the user is a human?.. fix it - don't just suggest reinstall.

Expect better from "the world’s #1 VPN".. the Linux experience is not as good as could be.

Я регулярно использую NordVPN на Win, Nix и Android уже второй год. Но этот аддон просто не работает от слова совсем! Я даже не могу пройти капчу, не говоря уже о вводе своих логин/пароль. Похоже причина в uMatrix и возможно других блокировщиках. Но я не собираюсь отключать их! Мне важна работа uMatrix.

it works but it is slow. it is best just turn on VPN with NordVPN for Windows 10. It is WAY faster. NordVPN connection through Firefox add-on for whatever reason is really slow.
