Constantly breaks, inconsistent.
Gets updated, breaks.

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!

Please allow to select cities like the desktop app, if possible then 5 stars :) thank you

While it works it's great, however most of the time after logging in I'm unable to change servers when one of them becomes slow leaving me with only the quick connect to the server I used last.

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.
