The extension keeps forgetting my login information but still connects to the internet. This means any security or anonymity is lost. You only need one single moment to be infected and you only need one single moment to lose anonymity.
To find out if you are still connected you have to click the ugly blue and green icon. So to stay safe you have to click this icon every time you think of it because it might have disconnected.
Support told me to reinstall the extension. I hope this works. If it works I would give this extension 4 stars because when it works it works good enough.
Blocking ads without the website being able to detect it would be a great feature. At this moment I don't see anything it blocks.

Very slow. Netflix Prime etc do not work. Paid for 3 years, promised a lot, delivered nothing. Have been breached as well

The connection to a specific country does not work.

I tried using it to log into HBO GO Romania (I am in UK) and it is not working. Worthless extension

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.
