Mozilla VPN is a consumer VPN service operated by Mozilla Corporation, the company behind the Firefox web browser. Launched in 2020 after a beta period as Firefox Private Network, the service represents Mozilla attempt to diversify beyond browsers while leveraging its decades-long reputation as a privacy-first technology organization.
The most distinctive aspect of Mozilla VPN is its infrastructure partnership with Mullvad, the Swedish privacy-focused VPN provider widely regarded as one of the most trustworthy in the industry. Mozilla VPN traffic routes through Mullvad server network, which consists exclusively of RAM-only servers that retain no data after reboot. This means users benefit from Mullvad proven infrastructure while accessing it through Mozilla own client applications.
Mozilla Corporation is a US-based entity, which places the service within Five Eyes jurisdiction. While Mozilla privacy policy for the VPN is relatively minimal in its data collection, the US legal framework allows for National Security Letters and FISA court orders that could compel data production. Mozilla maintains that it does not log user browsing activity, IP addresses, or connection timestamps, but the jurisdictional concern remains relevant for threat models involving state-level surveillance.
The service has undergone two security audits by Cure53, a respected German cybersecurity firm, conducted in 2021 and 2023. The 2023 audit identified a critical issue involving iOS private key handling that was subsequently resolved. Audit reports are referenced publicly, though full reports have not always been made immediately available in their entirety. The commitment to regular independent auditing demonstrates serious intent around security practices.
Mozilla VPN uses WireGuard exclusively. There is no OpenVPN or IKEv2 option. While WireGuard provides excellent performance and modern cryptographic standards, the lack of protocol alternatives can be limiting in environments where WireGuard traffic is blocked. The service supports multi-hop connections on some platforms, routing traffic through two servers for enhanced privacy.
The server network is relatively small at approximately 500 servers across 30-plus countries. This is adequate for most users but offers less geographic diversity than major competitors. Since the servers are Mullvad infrastructure, they benefit from the same operational security standards that make Mullvad a respected standalone provider.
Performance on nearby servers is strong, with WireGuard delivering minimal speed loss in most testing scenarios. Long-distance connections show more significant degradation, which is common across VPN services. The service does not actively work to unblock streaming platforms, and users report inconsistent results with Netflix, BBC iPlayer, and other geo-restricted services.
The client applications are fully open source and available on Windows, macOS, Linux, iOS, and Android. The interface is intentionally simple, offering server selection, a connection toggle, and basic settings without the feature density of competitors like NordVPN or Surfshark. Split tunneling is available on Windows, Linux, and Android but not on iOS or macOS. There is no browser extension — Mozilla VPN operates as a full system-level VPN.
The 5-device simultaneous connection limit is notably restrictive compared to providers offering unlimited connections. For households with multiple users and devices, this cap can be a practical limitation. Pricing is straightforward at $4.99 per month on an annual plan or $9.99 monthly, with no lifetime deals or tiered feature plans. A 30-day money-back guarantee provides a risk-free evaluation period.
Customer support is limited to email, with no live chat option. Mozilla support documentation is adequate but not as extensive as dedicated VPN companies. Response times can vary, particularly outside business hours.
Mozilla VPN makes most sense for users who trust Mozilla mission and want a simple, audited VPN without the complexity and marketing noise of larger providers. The Mullvad infrastructure provides a strong technical foundation, and the open-source client adds transparency. However, the US jurisdiction, limited features, small server network, and strict device cap mean it competes poorly on raw specifications against providers that cost less and offer more.
