I'm having problems since this afternoon (Sunday) with the NordVPN extension,version 2.30.2 updated 24th of May when I click on it a small screen comes to log in after that a screen appeared your logged in succesfully although nothing happens as I click the extension I see the same screen to log in again and the extension also stays light grey (not activated) I tried reinstalling the extension several times even reinstalled firefox,close all extensions all same result
I saw however that several more people here have the same issue with the extension and it's behaviour as I have,so I think since it was working fine before the new relase on Sunday it has something to do with the extention itself and not something on my end here,as this occurs on both my desktop pc and laptop but I hope it will be resolved soon as this is very annoying I also contacted support.nordvpn.com no solution ! I told them to look at the reviews here where many people have the same issue as I have : not being able to log in the NordVPN extension and activate it,I think the new extension is faulty because when I changed it to an older version of the extension 2.29.1 every thing works just fine again !
this is the link to the older versions ======

The login issue still not fixed. It looks like not just me. It seems like nord doesn't want to fix this broken add-on.

It works after I reinstall this add-on. Even if it works now, I concern the problem like this happen time to time. I hope your add-on will be stabilized soon.
----
There is similar problem like I experienced before happens today. I can log in but after I see the pop up 'you logged in successfully' the add-on still not logged in. I try to log in several times but the add-on keep shows 'log into your account'.
----
After I saw your reply and I reinstall this add-on, It works! thx for your fast support.
----
after I changed wifi router, it doesn't work. I can't log in this add-on. It says 'something went wrong'. Well, I can log in when I use other vpn however after it says 'You can now close this window', this add-on doesn't work.

Doesn't work jsut asks for password over and over again after first use. then the next time I open a browser it breaks and I log in and it just asks again Every time.

Same issue for me: After passing the authorization in the window that appears, the extension itself is not authorized, and so on in a circle to infinity.

Reinstallation does not help!

Now everything is working, ty.

The extension does not work. I can not log in. When I click on the extension it asks me to log in. When I click on it, a small window opens where I can log in. After the successful login a message appears that I can close the small window now. But nothing has changed. When I click on the extension again, the same thing happens. I am asked again and again to log in. I have uninstalled and reinstalled the extension several times. Always the same bug.

since this morning it is no longer possible to connect to the extension, I tested on 2 computers. I also uninstalled and reinstalled edit 1 : I installed the entire browser the problem is still present on 2 computers

problem corrected in the last version 2.30.3

Works great, if you don't mind having to uninstall and refresh everything every few days. Fast-ish, most of the time, when it stays up.

Edit: In response to developer response - I am reinstalling the app as instructed by NordVPN support.

4th year as nordvpn paid user(still 2 years remain to expire), and it is not working anymore! Fix it, please.

constant problems

Works well for the most part. The biggest problem I have is it will sign you out on occasion, I think after roughly a month, but the extension icon remains as if it were still signed in and connected. Pretty hard to protect your privacy when you get signed out without your knowledge or any warning.

Update: Looks like they may have updated the extension to show you're not signed in. But now it seems to have trouble logging in, or at least showing that you're logged in. I'll go through the login flow, wait a little and check the status in the extension, but find that it's still asking me to log in. Sometimes it resolves itself, sometimes I have to remove and re-add the extension for it to show properly.

Wanderful

Seriously bad, just like the Windows app. On the cellphone it is slightly better. This add-on simply does not work (most of the servers keep loading, then it creates a lot of problems with the logging in and logging out). They will probably respond to this review saying the same crap, hence I will not bother anymore and will pass to another service.

Works just fine, no issues so far. Logged in, selected a country, and just forgot about it.

Will not stay logged in. When logged out it will not even allow logging back in, just says something went wrong. Requires removing and re-adding the add-on.

Nord VPN is garbage. You have to keep disabling it in order to browse the internet, which defeats the entire point of having it. I requested a refund and they gave me the run around until it was past the "refund window" and then told me sorry but its to late. Absolute rip off, stay away.
