This add-on was causing me issues very often, like for others. Then I tried disabling all other add-ons and it worked! It's working even all disabled add-ons are re-enabled again so I can't tell what caused this. It may just be some other extension, it may be Firefox glitch or NordVpn extension issue. Until I figure this out it's 4 stars. Otherwise it's 5.

Logs you out without any reason, then asks for login and fails to do it correctly. Requires re-installation, and only after it finally works. I have only 4 other add-ons, which are some of the most popular on Firefox, all of them I basically mandatory for most users. So that dumb excuse from NordVPN developers, that it is not their fault, it is some bad bad third-party add-on interfere with theirs, is kinda funny in that case. There is no bad interference and even if there is, it is your badly written code cause this problem. Happens way too often, so I've cancelled subscription.

Does a great job when it works. Unfortunatly it cashes every now and then. Have to remove and reinstall it. a bit annoying... Desktop version works ok

Add-on not working (same issue as many other users). Works only once, when you remove and reinstall the add-on but the add-on immediately gets stuck again. Firefox is my main browser, so I have to cancel my subscription...

UPDATE January-2022:
No issues since using v2.40.0; it seems faster and I also like the new 'Pause' feature. Giving it 3 more stars.

June-2021:
It got really bad, broken Login! Claims "succesfully connected" to NordVPN in pop up window while exension icon shows it is not. NordVPN suggests to reinstall the extension but that's just a temporary fix; I'm getting tired of re-installing every week or so and perhaps it's time to trash it if NordVPN can't resolve it for good.

Extension is broken guys. Can't login, can't logout once logged in, and so you can't change anything. Everything works only a single time once you uninstall/reinstall the extension. But once you log in and make your selections, it reverts to its broken state the next time you start the Firefox browser.
NordVPN, you need to spend less on ads and more on development, because ultimately it's the users who will determine whether or not to keep using (ie. $$$PAYING FOR$$$) your service.

It's useless, I'm tired of re-installing the add-on every time I need to use VPN, this problem been there for months. I will not continue my subscription, better use Mozilla VPN from now on

Can not select server after login, I'm glad I cancelled my recurring subscription as it seems your developers can't even do a simple job right

Totally unreliable. Stops working frequently. Restarting doesn't fix it.

A log in is required.

After reinstalling the add-on, the icon disappeared on the task bar and never show up again. Other add-ons are showing okay. Installing another new add-on is okay so I guess it's the Add-on problem.

Toggling to enable/unable the add-on or reinstalling is not fixing the issue.

Have no idea how to use it at this moment.

It generally does its job but every few weeks it stops working and needs reinstallation

I had issues in the past with this extension but it seems to be working fine now. Hopefully the extension doesn't break again or have other issues.

very good vpn

Here we go again with the problems. It tells me to log in. I log in and it gives me the message that I have successfully logged in, but then it still tells me to log in. I have uninstalled and reinstalled it multiple times (which is something that I should not need to continuously do), and tried logging in multiple times after each reinstall. What is the problem here NORD???????

This seriously makes me question the security and reliability of your VPN that I subscribe to.

------------------------------------------

Old Problem - Today it will no longer allow me to log in. It doesn't even give me the option. When I click on the settings it then gives me the option to log out, but also will not work. It was working great until today. Something has happened and needs to be corrected.

I received a message asking that I reinstall Nord. I had already tried that multiple times, however today it started working again. Who knows what was going on, but it seems to be ok now.

cant log in

DO NOT TRUST THIS ADD ON!

You just can't trust this add on. The icon shows you're connected but it randomly disconnects in the background so you think you're going through the VPN but you aren't. This is even worse than it just not working. Tried uninstalling and reinstalling but it still doesn't connect.

Just not WORKING, the connection is so slow and can freeze for 10 seconds.. (the plugin worked well on chrome btw), my VPN is not usable currently and I will be forced to cancel my subscription if this problem is not fixed.

best vpn

Has gotten really flakey for about the last year w/ Firefox on Win10. Android version has some issues too hanging but its a lot better than the windows version. Nord's customer support solution is to use their whole computer VPN and not the FF plugin. I can't do that. Not very fast either.

Fix it.
