good

Excellent performance, no lagging.

great add on vrey simple but works..

Super easy to use, everything's very convenient, though I noticed that still use more app than this extension

Easy to use, works great and delivers impeccable excellent security.

It has thousands of available servers scattered around the globe and I have never had connection bugs. I even couldn't tell a difference in my speeds after turning on the VPN so I was able to browse securely without slowing down the loading speeds of any web pages..

Great speed, very user-friendly layout

Works perfectly. Very easy to use and offers a sufficient number of servers for my needs.

I've installed this add-on on both Firefox and Chrome as I use Chrome for hulu and with both browsers open, Firefox working hard with multiple tabs, and chrome connected to the US and streaming hulu in HD i am very happy with the results. (Speedtestest.net on Firefox 570Mbps, Chrome with NordVPN set to USA 360Mbps at the same time. We have 1Gbps from our ISP here in Poland.

Noice!

Even though the app itself is easy to use, this is even more convenient. Also, it's one of the best VPNs out there.

Would be great if it didn't freeze or crash Firefox on a regular basis.
It doesn't do this in Chromium-based browsers so the fault could lie with Mozilla. But you've been warned.
