Mozilla VPN is nothing but a rebranded Mullvad VPN with an Mozilla Logo on top of it.

Reasons why Mozilla VPN sucks - in a nutshell.

• Price differences between Mull and Moz. Moz is more expensive and offers overall nothing new or even less.
• Mullvad is longer in the business, trusted an an expert in the VPN field.
• Less physical servers and depending on the region, overall slower.
• Only front-end.
