Updated review from 3 stars to 5 stars:

They reworked the login system for this addon and now it stays logged in. With the previous login system you'd have to relogin like once a week and you couldn't save your login credentials either.

With that being fixed, I have no real complaints about this addon. Sometimes you get slowdowns but that has been the case with every VPN using any type of client I have tried. Addon or dedicated desktop app. Slowdowns happen.

Why is every time I have to enter username and password to use NordVPN when I open the Firefox browser? This doesn't happen on Chrome and Microsoft Edge.

needs to connect to a VPN that actually allows you to browse the web.

L'extension bloque le serveur proxy de firefox, donc j'ai dû le désactiver pour pouvoir me connecter

It works well but i'm missing one important convenience "tweak" or user comfort/convenience feature.

In the world of password managers, please allow for the user to have automated login details to be enterered. Right now it does not allow easy copy pasing of login details because clicking anywhere outside the plugin window will close the window and clear the field you've already filled in.

It's highly annoying having to type everything everytime you wish to login with the browser plugin.

Good

Doesn't work anymore. Yes I have logged in. Yes I've paid. Yes the regular app works. They screwed up and like all modern companies they want to sit and collect cash instead of fixing their screw ups.

This extension uses very slow animations to open the focus-exclusive overlay of its interface. If you don't interact with it directly, it dismisses itself.

Both of those issues are egregious UX failures that need to be addressed. The animation is unnecessary and makes your extension look poorly made; which it is. The fact that the overlay doesn't remain open is even more absurd. I keep my account info in a vault, so I am forced to manually type my email after pasting my password because if I were to leave the form it would just evaporate, clearing the form as well--and to make it worse, it would show the slothful opening animation again.

Partially UX, partially just terrible programming, is that the extension requires you to sign in repeatedly even within the same browsing session, which means it doesn't have good error recovery, connectivity state detection, sleep detection, etc. It would be reasonable to expect that once you sign in with your account, you never have to log in again unless a significant passage of time between uses is detected, like 3 months or more, or your subscription lapses.

None of these issues are difficult to solve. The first two could be solved in two lines of code, I'd bet. The sign in issue seems to happen to far too many people to be an isolated issue.

Perhaps you should consider that not everyone uses their browsers the same way you do. I leave Firefox open for maybe a month at a time, literally until Windows forces me to reboot for updates.

I put my machine to sleep at night and don't manually disconnect from a server in the add-on. That doesn't mean I should be signed out. That just means the add-on should reconnect the next time it "ticks" when the machine wakes up, or when there's network activity in Firefox.

Me too completely broken since recent update

NordVPN works well on all other devices but this extension on a RaspberryPi won't work. Try logging in to NordVPN with correct credentials and it says something has gone wrong.

Breaks proxy query when enabled.

It's really not suitable for ChinaI can't log in yet.😭😭😭

Your servers randomly stop working. Was connected to bg39 until that stopped working. But because the login goes through the VPN I can't log in to change it. This is braindead design.
