Mozilla VPN is a security and privacy software developed by Mozilla. Previously known as Firefox Private Network and Firefox VPN, this app secures your browsing activity and identity. It was only available in closed beta, and it can only be accessed in the US region before. But, as time goes by, they were able to devise a fully-functioning VPN service. It is offered in six countries—the US, the UK, Canada, New Zealand, Singapore, and Malaysia—with more regions coming shortly.
