Hello,

This is just impossible. An extension cannot be installed without human interaction.

Have you tried all the servers? I recommend you to tried the free server in UK, we changed the IP yesterday so it should bypass restrictions.

Hello Sporitus,

Our service is free, but there are premium servers. If you don’t want to pay you can connect to the free servers.

Hello Ayaz. There is no way you are disconnected before the limit time. We have a time limit so that our servers are not overloaded. If you want no limit and utlra-fast servers I suggest you to subscribe or to contribute to the purchase of free server in donation.

In any case, we have more free servers than other VPN services. We intend to offer an unlimited service subject to free registration on our site.

If you need help, or have another request contact us at sandvpn@sandvpn.com.

Best regards,

The SandVPN Team

You cannot find a VPN on Firefox addons without install an external software. If you're looking for VPN protocols (openVPN, Wireguard, IKEV2) you won't find them on Firefox or Chrome because they can't be implemented with the Chrome and Firefox APIs. So my advice to you is to stop looking and turn instead to Windows, Mac, IOS or Android applications.
