Great addon to complement the Nord VPN Desktop app in case you want to control when you activate VPN and which websites are whitelisted, but it has few issues:

1. There is no easy way to whitelist websites, apart from clicking on the extension, going to settings, going to Bypass List, copying and pasting the website url (needs to have http:// otherwise it won't work) then saving and reloading the website. They need to make this easier by having an option while right clicking the page or by having a simple "add to whitelist" button in the extension menu, like ad blockers do.

2. There are to blacklists. It would be useful to have the option to run the extension in either whitelist or blacklist mode and select which websites to be tunnelled and which to be not. Right now there is only whitelist option.

3. Ever since the recent Firefox update to version 89, the extension randomly stops working, it will not login into the account anymore. The solution is to remove the extension and add it back again which is a pain because all the whitelisted website are gone and there's no obvious way to back them up. I'm not sure if it's an additional Firefox settings that is causing this problem or the Nord VPN extension hasn't been updated yet, but once every 2-3 days I have to do this.

Overall I'm happy with it, but Widnscribe has more settings and is easier to use. Not as reputable as Nord VPN, but Nord could make the extension a bit more feature-rich.

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.

It is not quite 5 stars.

If it had a feature where you can have a custom dns on the add-on just like the windows client that would be great

this is the good vpn but any this extension not fully running

It's finicky at best. will sometimes wither take a long time to log in or never log in at all, which is annoying because it signs you out of your account every time the browser is closed.

after changing the password, the firefox plugin does not accept new settings, the main application works without any problems with the new password

I turned off all firefox add-ons and then logging was positive

Needs improvement. Favorite countries could be added.

Sometimes the complete list of countries does not show up, you have to logout and login again to see the whole list but somehow countries from recent connections work. So, a simple favorites list which is kept locally will do a lot more than recent connections.

edt: Once more, I propose adding favorite countries/servers to prevent deleting cache, cookies or logging in-out everytime that error occurs.

Sometimes work correctly but from time to time I need to reinstall in order to work smoothly

It keeps logging me out when I'm not using it

I have the same problem for "The proxy moz-proxy://us8107.nordvpn.com:89 is requesting a username and password. The site says: “NordVPN”". I change the account with a friend, i reinstall the add-on, and i still can´t solve it. Please help meee

Why does the add-on require me to allow it to run in private windows? What if I don't want to use it in private windows anyway? Does it just want to collect some data when I use a private window, which exists to prevent tracking to a certain level? Kinda ironic for a VPN/Proxy Service...

Edit because of the Developer response: "You may choose to enable or disable this permission when installing the add-on, as well as in the Menu > Extensions section." No, I can't and that's the issue: If I do this the extension won't work any more, if I click on it it just tells me that the "Permission to run in private windows is required by Firefox for the extension to work." even in regular, non private/incognito windows.

A nice, functional add-on, but lacking several features. Unlike the desktop app for Windows, it does not have a killswitch for if your connection drops for whatever reason, something I find pertinent with web browsers especially, since if a connection is lost on many sites an auto-reconnect will be attempted. The server-browser is very lacking, with only the ability to choose countries rather than specific servers, as well as barring the specialty servers available in the Windows App like Dedicated IP. The total lack of the features (or the manner in which they are hidden, if they do exist and I simply cannot find them) is disappointing. it is good for on-the-fly IP switching, but for privacy? Not enough control to be useful.
