Worst coded extension ever. Sometimes the GUI thinks you're disconnected despite you're connected, so you need to relog each time you use your browser. Same problem on the extension from the same company for other browsers.
Sometimes says you're connected to a VPN server despite you're not : big security issue.

this is the best vpn

This addon does not remember the authorization. After restarting Firefox I enter the login and password again.

I'm running Linux and this add-on greatly simplifies my connection process for secure browsing.

Edit: Connection issues are difficult to resolve using this add-on. Feels like Nordvpn traffic is very slow like they are overloaded at times. Still works ok now and then

Works but too basic. Needs further improvement i.e. remebering previous connections.

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. :-)

instead of remembering my login and country i have picked every time i open FF you have to reenter your credentials and connect to the country you had chosen before, again manually.
