VeePN works well and securely for me on Firefox, with Ublock Origin disabled. Running Ublock Origin along side of VeePN causes a DNS leak, revealing my ISP. I don't have this same problem using Chromium-based browsers (Edge, Dissenter, etc.), where I can run VeePN and Ublock Origin together. Not sure why this is, only that it's happening. This same issue occurs with Ublock Origin and other VPN extensions on Firefox, so it's not exclusive to VeePN. Hopefully, Ublock Origin and/or VeePN will come up with a fix for this, so that both extensions can be used together.

this is the best VPN add on present on firefox

It gives only a few hours, and then stops working, demanding (forcing) upgrade to Premium.

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!
