So far, it's not apparent that it is even in use.

Up until recently i haven't had any problems with NordVPN, but that's changed in the last 2-3 months or so. Recently they've started using LOCAL ISP's IP addresses for their services, which means that their prime selling point, being security, anonymity, and access to local blocked services and websites is pretty much null and void.

DO NOT USE THIS EXTENSION, as you do not have control over what IP your traffic is routed, and there's a good chance they'll use local (from the same country you are from) ISP's to assign you an IP.
IMPORTANT EDIT: Not just that, when refreshing your IP, or when the application randomly changes IP, it exposes your IP/network to your ISP, without any apparent killswitch built in. Citation needed, because there is a chance your network is still encrypted, but i somehow doubt that.

They'll say 'we choose the IP based on what's best for you', completely disregarding the problems with that. IP's change randomly quite often, which means that there's a chance that you won't even notice you've rolled into a local ISP when it happens. Refreshing your connection will often give you the same exact IP address as well, and you don't have an option to select a specific IP address in any way, shape or form.

Bypassing local restrictions is one of the number one reasons to get a VPN these days, and failing to deliver on the promise of that service is to fail as a VPN service.
I will not be extending my subscription past march this year (end of term), and i will not be returning to NordVPN.

I don't believe a 1 star review is warranted, since the service, operationally, functions quite well. The speeds are decent, and the ease of use is tempting to say the least, but the fact they're using local (national) ISP's for their services, paired with some of the other security concerns that have come up in the last 2 years regarding NordVPN (look them up if interested), i can not in good conscience recommend this extension.

Encryption alone means nothing if you cannot access services that are locally blocked by IP/DNS.
If you're looking for a good VPN service, there's better ones out there.
I for one, can no longer trust NordVPN with the security of my internet traffic.

Speeds much faster with this extension but the extension is ridiculously limited like their service. You hit refresh to change another data centre and you always get the same one or two despite the data centre having more than 50+. This tells me Nord doesn't have as many as they claim

linux. ubuntu studio 20.10. firefox. nordvpn addon. suddenly stopping links opening and preventing navigating on some sites. generally great, though. I hope the developers are working on these gliches.

This add on really slowed my computer way down. Even after I shut it off it was still running in the back ground,had to completely uninstall it and after I did my computer sped back up to its normal operating speed.

Not being able to specify a server

0 functionality without payments.

Nord Vpn is GREAT.... Yet, the extension on firefox keeps loading as it needs to connect to the service so I can log in.... It never loads it just continually spins the wheel waiting to connect.
I have tried disabling it, re-enabling it still does not work..

I'm sure I would love this extension if it worked. Unfortunately, since it does not run login through an obfuscated server almost every work and public WiFi network blocks the ability to log in through the extension.
Nord, please add this as a feature. It's absolutely excellent in the app.

in windows it doesnt work and also in extention mode

The extension requires login every time FF updates, can't use saved passwords, as well as having infinite spin issues if you disconnect from the VPN on one session and tries to reconnect on the next session. Pretty poor User Experience tbh.

depuis des semaines l'extension ne fonctionne pas je ne me réabonnerais plus trop de bugs depuis un moment

Need to reinstall this frequently to be able to use it on ubuntu 20.04

Its fine when it works, but it really enjoys logging you out. Recently it wouldn't let me log back in so I tried re-installing the add on but now its icon doesn't appear in the extensions bar (not even the drop down menu for overflowing extensions) so I can't log in or anything.

It does however appear in the add-on manager but you can't actually use the extension from there.

I would just use the full PC app, but it had a habbit of giving me BSODs when in use, especially when playing glames, even if I had them blacklisted from using the VPN.

It stucks very often last weeks. Not possible to change the server or even log out. Only reinstallation helps. And connection also poor at that time.
