The firefox addon is terrible. If you choose 3 different countries for your VPN, it won't EVER load the country list again, you'll need to uninstall and install it again. Needless to say that it's not acceptable.

totally unnecessary add-on and i would personally suggest Mullvad over Nord

reply to developer:

sure, i'll provide more detail ... who ultimately owns Nord?

Does not work anymore. Although I have a paid account I just can't use it anymore. It says it can't connect to their servers and it does not show any country list. I can however connect through the desktop app without problems.
Support Bot at support.nord-help.net does not have a option for firefox addon.

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.

this thing does not connect, keep getting the same failed to connect error...
