Despite offering limited features, Mozilla VPN is a perfectly safe and secure service. It provides enough security features to conceal customers’ activity. The VPN is immune to all DNS and IP leaks. If your VPN connection drops, it gives a Kill-switch feature to hide the data from your ISP. There’s no protocol selection procedure in the Mozilla VPN.
Although, the WireGuard is the only available protocol on all platforms, which is the most advanced and fast. So, there isn’t any reason to complain. The VPN uses ChaCha20 encryption, which is not the advanced one like the AES-256. Talking about the advanced features, the VPN uses an Ad-blocker, a Double VPN feature, and a Split-Tunneling part. Overall, Mozilla VPN offers a safe and secure service to its customers.
