No Server selection options...which means if you connect to a sucking server it's unlucky of you :) Dunno why recently I have to log in every time when I open my firefox... Every time I ask NORDVPN support team all I get is : there's nothing to help. This app is an orphan. All you can do is to pray for someday it will be fixed automatically or get back to the NORD app and make your whole system on VPN which is annoying enough since some apps are not working under vpn status!

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.

Gets stuck a lot. Sometimes requires a https login for some proxies. The speed is very good, no ip leaks. But the extension by itself is a problem.

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.

It doesn't keep me logged in
