"The proxy server is refusing connections."
Same problem as other people mentioned. I get logged out, you can't log in anymore and the internet traffic is still blocked.

edit: I updated my browser and reinstalled the add-on. It works afterwards and after a few days I have the same problem again.

Easy to use, works great and delivers impeccable excellent security.

It has thousands of available servers scattered around the globe and I have never had connection bugs. I even couldn't tell a difference in my speeds after turning on the VPN so I was able to browse securely without slowing down the loading speeds of any web pages..

When it works, it works well, but every so often, Nord signs me out and won't accept my password. It blocks all connection to the internet and there is no way to sign out. If I disable it, I can't then re-enter my details. The only workaround is to keep uninstlaling and reinstalling it. Their helpdesk have been unable to provide a solution.

Nice add-on but why I got logged out after I close Firefox. Isn't it possible that I got automatical got logged in when I start Firefox?
I logged out on the add-on and closed Firefox. Then restarted and opened Firefox. I had to log in again...
My OS is Linux Mint.

Update: It works after following your previous instructions! I can see that when I open the NordVPN website. However, the add-on of NordVPN does not respond and it seems that I am not connected to NordVPN. It would be nice if you could see directly in the add-on that you are connected.

Working smooth and quick for my work. Recommend.

Great speed, very user-friendly layout

Works perfectly. Very easy to use and offers a sufficient number of servers for my needs.

Convenient add-on if you mostly need a VPN for browsing

Man muss nur bezahlen wenn man deren Guides nutzen möchte.

I've installed this add-on on both Firefox and Chrome as I use Chrome for hulu and with both browsers open, Firefox working hard with multiple tabs, and chrome connected to the US and streaming hulu in HD i am very happy with the results. (Speedtestest.net on Firefox 570Mbps, Chrome with NordVPN set to USA 360Mbps at the same time. We have 1Gbps from our ISP here in Poland.

Noice!

Even though the app itself is easy to use, this is even more convenient. Also, it's one of the best VPNs out there.

The addon works quite well, it really simplifies the use of a VPN

i've used it for whole year, works good but sometimes slow HOWEVER if it often cannot connect to specific regions and/or randomally logs you out after closing the browser, requiring you to log out and log in for it to function properly.
i wanted to give it 2 stars but then I saw the "developer" rushing quickly to every negative review to spam the "contact muh support"
