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.

NordVPN works very well and seamlessly with Firefox. I do not use it all the time, but when I do it works well. Moreover, it is compatible with my Phone (Android) where I use it most, especially where there is free WiFi (stores, airports, etc.). I also use it on field work in countries where there are restrictions on internet use, for example when browsing for pages that are restricted or not allowed by the government.
I did not want a free VPN since I do not fully trust them and I hate ads. After some research Nord VPN seemed the best one, and I have been happy ever since.

The #1 VPN service available hands down. You can literally be in any country in the world anonymously without hackers or the government sticking your nose in your business. Your internet activity and security is completely safe on all devices.

Не работает, значка нет, настроек тоже нет

We using NordVPN from the Island Madeira/Portugal many Times. In Spain or Netherland we used it too. Never had problems with watching German TV on Tablet/LapTop, working with a LapTop, Cellphone on the Internet incl. OnlineBanking, etc..

"The best VPN" more like the most shadiest one to ever exist
