Don't fucking bother using nordvpn. Firefox addon support is crap even in 2020. I regret recommending this to couple people.

The stupid addon keep disconnecting and request another auth. wtf

It's 2019 an it's still happening. sucks. Keep doing 'requesting a username and password. The site says: “NordVPN”'
Why can't they just publish their sources on github!?

Good privacy and security

I've used NORD for years and have zero problems and some minor tests show it's secure. Does what I want. Works on Window_crap to. I use it on my Android it works.

can't login at china

Not logged-in in my browser. I only use in 2 device.

Good

Unless I'm doing something wrong, Their one-size-fits-all linux package is not suited for all the distros I use, and when I have to configure several VPNs accordingly, the time adds up. The add-on is an elegant solution in my case

Terrible service that now won't let me view email messages.
