Keeps on randomly loosing credentials on all the environments : ios, android and the firefox extension. I have a 3 years subscription and I can't really use it. I went back to Windscribe who is much cheaper and no problems of this kind. It is a pitty because the net speed provided by Nord VPN is very good. I will come back when you solve this problem. I will not take another subscription to your service

无法登陆使用，Unable to login for use

Of all the VPN services, this is the most disgusting! The support team is full of money-hungry geeks! They don't want to return the money! I wrote a hundred times that their add-on doesn't work, constantly requires authorization, crashes, they don't care! Don't buy this shit!

Doesn't work with my DNS-over-HTTPS service. When I enable it, I get a error that Firefox cannot find the proxy server. So this does nothing useful.

this doesn't work in china.

Every single time I update my Firefox App, which is every night (I use Firefox Nightly), this add-on decides to log out and I have to re-login using my password manager each time. So infuriating. Nord, FIX YOUR APPS please!

One random day in the middle of a browsing session it started giving me an "Unable to find the proxy server" if I was connected to NordVPN. It won't load anything. Haven't been able to use it since and only with Firefox. Chrome and Safari function just fine.

Logs out very frequently

It sucks - I cannot pick servers to connect and once connected if I try to connect to another server country it don't load / work. Al I get is a connect option to UK and if I try to load any other country nothing loads whatsoever I just get a blank screen and no other country's load. I have all latest updates installed.

All servers give the ssl sequrity error and name/password request (no ability to connect)

1) I have successfully logged in to the expansion.
2) I select a server or click "quick connect".
3) "Connected to *Сountryname* !
4) A window appears "Proxy moz-proxy://**9.nordvpn.com:89 asks for username and password. The site reports: "NordVPN"
5) My username and password do not fit
6) "Connection failed."

What was I paying for?

P.S.: My internet connection without VPN is perfect.

I have to login every single time. That's so annoying that I don't use it anymore. I also miss a option to select a server.

The extension keeps logging out after hours of use. This happens daily. It is very annoying to have to relogin very often. Sometimes the extension is even enabled (and traffic is going through NordVPN), but I need to log in to turn it off! The TunnelBear extension does not have these issues, plus it has a handy keyboard shortcut to turn it on/off.

Extension sucks. You don't even get to choose your servers. You are given a server for that country instead which is completely dumb because it limits you for all the servers they have that you can't even choose on the extension, unlike the app itself.

On top of that, you can't even favorite the server, or in this case you can't favorite the country that picks the server for you.

Ugh... I'll just uninstall the extension and stick with the Application instead. Don't understand why developers decided to release an unfinished extension. That's such a half-ass work.

This extension is awfull. The VPN itself is good, but when I enable this extension on firefox I lose my conection until I disable the VPN again. The Windows app works fine, but I don't want to use VPN on the whole system.

Win10 Professional

Pros:
It's useful when it works.

Cons: (all intermittent problems)
After turning on my PC Firefox cannot access anything until I've disconnected and then reconnected NordVPN.
When I try to change locations it sticks at loading servers and never progresses beyond that.
After powering on the PC, NordVPN has logged me out.
Logging in is a pain, I can't copy and paste my username/password because as soon as I click away the login window closes.
I've paid, so I'm stuck with it.
Nordvpn support is quick to respond but their answer is just a workaround (remove/reinstall the add-on). I did that and 2 days later the server load fault is back.
It has now been a month (longer for others) with no progress on the reported faults, dropping to one star.

UPDATE: If you want to purchase NordVPN for the Firefox browser Extension, SAVE YOUR MONEY. It is very frustrating and support wasn't helpful.

This extension has been problematic from the start. It took a lot of farting around to get it to work when I first installed it and for whatever reason it logs out for no reason. NOW I can't log into it and if the extension is enabled none of the websites will load and you are presented with "Unable to find the proxy server". Disabling it then enabling it doesn't resolve the problem nor does restarting Firefox. To make things worse support.nordvpn.com is useless, I can't find any information on the extension for Firefox and it does not provide any way of contacting NordVPN Support. I moved to Firefox for privacy/security reasons and signed up with NordVPN for the same reason, I think it is time for a refund and go back to PIA.

Doesnt work with Firefox. :(
