The extension works well for me since the last year.

Ok, works fine with linux mint 20 and firefox

this is the best vpn

nice catch

Se l'estensione non viene installata, Installare la versione FireFox 66.0.4 o fare l'aggiornamento a questa versione e reinstallare l'estensione.
If the extension is not installed, install the FireFox 66.0.4 version or upgrade to this version and reinstall the extension.
Buono, Good!! Intanto aspetto che NordVpn si possa vestire da firewall/router software (forse...desiderio...), ma anche un IP/Port Filter e url filter non sarebbe male. :-)

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.
