Thanks to this VPN and the author, we can see the world under the dark curtain

Оно просто ничего не делает...

It doesn't work on firefox 56.

目前非常好用！有免费的几个端口可以使用，付费可以获得高速、更多的端口，如果只是刷刷网页而已，免费的网速完全够用！

不论在firefox还是chrome都很好用，速度不错，关键是不掉线！

I have probably tried all VPN extensions and addons out there. VeePN delivers big time, in terms of security and speed. AND IT'S FREE!!
If i ever thing of having a premium VPN membership, I will not even try and see other apps out there. Great job from the developers....6 stars addon!

There is dns leak.

Отличное расширение с хорошей скорость VPN соединения, даже на бесплатной версии с головой хватает 2 стран. Рекомендую всем попробовать:)
