does not work at all, my ip is still same, tested on several ip checker websites, i don't know is this only not working on xp and firefox 52.9.0 or even on newer system, useless! actually this could be my primary ip proxy which blacklisted you, so 403 forbidden maybe, so vpn is automatically not used

badly

Very good choice for security and unlimited and free access

There is registration.

I don't know what this is or what it does, but it's definitely not a VPN. Installed, tried to connect, it showed me some nice circles for about 10 minutes, then it connected and... nothing. It doesn't connect you to any VPN server. I think the developers should read a bit more about the difference between a VPN and a useless Firefox app.
PS Germany and France are NOT in Africa.

fckin scam! I allegedly successfully connect to a server, but iplocation.net displays my actual location! good that I check. It's so hard to find a working Vpn add-on !
