Thought it was meant to be a free add-on for firefox but when you click to register you are than presented with a page from NordVPN wanting payment. Slightly confused. Is it Free or Paid?

I thought this might be an easier option than having to change the firefox settings each time the server was changed- by Nord VPN I must add- BUT this is just an annoyance. Have to login to the addon every.single.time.the.browser.is.opened.
Does it remember login and password? NO!
Is it excruciatingly slow to allow the login? YES!
Does it drop out regularly? YES!
Does it automatically reconnect? NO!
This couldn't be less user-friendly if it tried. In fact I've created a firefox account just to voice this opinion, which is how much it's annoying me. SORT IT OUT NORD VPN!!!!!

I suggest you avoid NordVPN since it has serious security issues. By default it does not block network traffic when the connection to their server is dropped which leads to leak of your traffic. It can be turned on but the issue is that it is not default. Also in default, it does not change your DNS servers, which has the similar issue as above. Thus in default settings, it is as insecure as if you were not using any VPN at all (since you cannot forsee the connection drops to their servers). Second, even if you change the settings, there is no guarantee that this will stay so, updates or you yourself can delete the configuration without realizing what you have done and then go on browsing thinking that your security is tight but it is not. Any security product that is provided with such lax default configuration is a bad product. Lastly, they could not explain the protocol difference or how to determine what protocol is used when connecting to their servers as opposed to other solutions which also provide network traffic blocking and dns by default.
To update based on the request from the developper. Your customer support effectively said that you do not care what the default settings are since users can change it, again, this is the problem in itself. And again, you claim a secure privacy oriented product, this has to reflect also in its default settings. Without kill switch on, any vpn for security and privacy purposes is almost completely useless, the same goes for DNS.

Is there any new update? It keeps getting disconnected, really annoying. Please check what's wrong and make it stable and improve it. Windows desktop application is working fine for me, this proxy extension should be repaired/updated.

the extension crashes every time in private mode (ff 67.0)

Diferente do programa que funciona perfeitamente, esta extensão é um fiasco infelizmente! Por muitas vezes voce é desconectado e fica pedindo pra logar novamente. Uma pena que seja tão ruim. Vamos aguardar futuros updates deste addon mas HOJE (dia 23/05/19) não recomendo o uso. É pedir para ter dores de cabeça pois fica caindo toda hora a conexão...

Worst coded extension ever. Sometimes the GUI thinks you're disconnected despite you're connected, so you need to relog each time you use your browser. Same problem on the extension from the same company for other browsers.
Sometimes says you're connected to a VPN server despite you're not : big security issue.

This addon does not remember the authorization. After restarting Firefox I enter the login and password again.

instead of remembering my login and country i have picked every time i open FF you have to reenter your credentials and connect to the country you had chosen before, again manually.

Don't fucking bother using nordvpn. Firefox addon support is crap even in 2020. I regret recommending this to couple people.

The stupid addon keep disconnecting and request another auth. wtf

It's 2019 an it's still happening. sucks. Keep doing 'requesting a username and password. The site says: “NordVPN”'
Why can't they just publish their sources on github!?

can't login at china

Terrible service that now won't let me view email messages.

V2.8.4 Update - still frequent disconnects (not as bad as before), but reverting back to the stable V0.9.21 - I cannot afford for a site to half load then the VPN drop connection - this is not good for security - This is firefox fully updated with NO other add-ons or plugins.
Update for V2.6.3 - Still not usable. Connects, then prompts for username/password (firefox dialogue), can maybe access a single site, then after a few seconds dialogue says Failed to Connect, please try later. This is now every version except the initial release that does not work for me. Initial release still works perfectly with no issue, so back to that one again....... Original Review: Latest two updates (2.4 and 2.41) not usable for me. Logging in and connecting keeps kicking me out saying 'session limit exceeded, try again in 15 minutes'. Have logged with support, but meanwhile have reverted back to v0.9.21 which does have this issue and keeps me logged in with issues.

It freezes when I try to choose a country. And it is really slow when I try to open it.

When I try to enter my password the extension window disappear, impossible to sign in

First off, this add-on is not free. You need to make an account on their website and pay for a subscription to their VPN service. Secondly. if I am connected to their VPN service, why would I need this add-on? I have nothing against NordVPN but geesh!

This extension is extremely resource heavy. Any interaction with this extension takes about 3 seconds for anything to actually pop up or react. I would stick to a desktop client as opposed to this extension.
