I have the perpetual login issue as well.
There's no "Cancel" button available as support here suggested.
Terrible experience, seems like I need to seriously consider changing VPN provider

Plugin simply does not work. Whenever I log in the UI keeps asking me to log in again, as if it doesn't realize I just did. Yes, I have contacted your customer support (they said there was nothing they could do), cleared cache, reinstalled plugin, disabled all other plugins/extensions, and it still does not work.

Перестало работать

It does not encrypt DNS queries that are leaked by Pihole. But NordVPN extension works in chromium based browser.

the login problem, man it is horrible! i know i already successfully logged in, the setting shows log out button. but the front interface only display log in option. check it on chrome, it is fine. please fix this. i cant use this add-on.

It's stuck in a login loop since weeks. Can't log in, says it does but it doesn't, so can't use it. Go away. Broken. Period.
Problem appeared for me with recent update that use a popup that get you to login.
Bro, it's not even practical. Anyway.

Did all the basic stuff, meaning, uninstalling/installing, clearing cache ect. You know the drill. No fix, and if such operations do not work, the fault's not on my end, as a basic user i should not have to mutate into a nerd goblin and do a rain dance around the system files of my computer in order to find a fix.
People are paid for this.
I mean (I hope...).
Paid to do the job.
Not the goblin one, dammit.

Go see the other reviews, most recent users talk about similar issues.
Also no solutions given openly, unless by adressing a ticket to support team, which i have nor the time nor the will to do.
When most reviews talk about a said problem it's not about specific cases anymore.
So, dear sweetie Nordie, i don't need a ticket or a kiss on my forehead, i need an update, or the choice to go back to an older version, when it worked smoothly.
Those were good times.
Bring'em back.
Xoxo.

The extension requires login every time FF updates, can't use saved passwords, as well as having infinite spin issues if you disconnect from the VPN on one session and tries to reconnect on the next session. Pretty poor User Experience tbh.

depuis des semaines l'extension ne fonctionne pas je ne me réabonnerais plus trop de bugs depuis un moment

You do two logins in the morning, you do two logins at night. You do two logins in the afternoon, it makes you feel uptight. You login twice in times of peace, and two in time of war. You login two times before you login two times, and then login two more.

Don't waste time replying to this, devs. Just fix the login loop already! This is just silly now.

Ne fonctionne pas. La "simplicité" dont se vante cette entreprise se résume a devoir batailler avec un service d'aide injoignable et qu'on a pas forcement envie de joindre. Désinstallé direct. A fuir donc!

Works ok but you better hope the node you are closest too hasn't been banned by Netflix or Disney+ because you have only the one choice per nation... The desktop app lets you choose between multiple nodes within a nation so it's better.

For the past few days/weeks this addon has made browsing a painful experience.

Everything slows down to a crawl in random intervals. The addon says that I am not logged in but even after I log in (and I get a message that I have successfully logged in), it keeps saying that I am not logged in. Changing servers also does not work because the addon is unable to retrieve server list.

I have been reinstalling the addon several times every day, which helps for a while but sooner or later it breaks again. I have also cleared cookies between reinstalls, as suggested by the "developer" but, unsurprisingly, this did not help either. Firefox is always up-to-date and I am not using any addons that might interfere with a VPN addon.

Similar behavior has been reported by other users and the only "solutions" provided by the "developer" are to reinstall addon, clear cookies or reinstall Firefox. They are either incapable or unwilling to fix the actual underlying problem with the addon. Instead, they try to shift the responsibility to the user. The amount of users reporting these issues is indicative that this is not an isolated user issue but rather a programming issue.

To other users: If you value your time and mental health then steer away from NordVPN firefox addon.

To the "developer": If your addon requires daily reinstall while multitudes of users are experiencing the same problems, then there is clearly something wrong with your addon. Don't bother responding that I should try this or that, I have already tried it all many times. Instead, do your job and fix the addon!

PS: I am also using the Chrome extension and it has been working well so far. Quite a stark contrast to the Firefox addon.

Completely useless with the issues around the login loop. Yes I've disabled all other extensions and plugins, yes I've cleared the cache, yes I've been to see the holy monk in the temple at the top of mount Wasteyourtime. The extension simply doesn't work and until it does, it deserves 1 star.

Terrible buggy add-on that I have to keep deleting and reinstalling.

No I don't want to contact customer support, just fix the add-on, there's obviously some major issues with it.

Need to reinstall this frequently to be able to use it on ubuntu 20.04

Cleared cache and cookies. reinstalled plugin, but still gets stuck in a login loop. Thanks for nothing NordVPN. This should have definitely been found by tests, before making a release... Not happy.
