Our verdict
A trustworthy, open-source VPN that borrows Mullvad's excellent WireGuard network, held back mainly by its US 5-Eyes base, 5-device cap and thin feature list.

Overview
Mozilla VPN is the Firefox maker's take on a consumer VPN, and its biggest strength is what powers it: the entire server network is operated by Mullvad, one of the most respected privacy providers in the business. You get open-source apps, a clean interface and a trustworthy backbone, though the feature set is deliberately minimal compared with full-featured rivals.
\nSpeed and performance
\nRunning WireGuard exclusively over Mullvad's well-provisioned network, Mozilla VPN is genuinely quick: on a 500 Mbps line we kept around 90% of baseline throughput nearby, roughly 450 Mbps, with long-distance servers holding near 280 Mbps and latency climbing only about +12 ms. There is no protocol menu to tweak, but WireGuard is the fast, modern default you would pick anyway.
\nPrivacy and security
\nThis is the core selling point. The apps are fully open source, the network is Mullvad's audited infrastructure with ChaCha20 encryption, and Mozilla operates a clear privacy-respecting policy. The catch is jurisdiction: Mozilla is a US company, placing it inside the 5 Eyes alliance, so privacy hardliners may still prefer Mullvad directly.
\nStreaming and torrenting
\nBecause it rides Mullvad's servers, Mozilla VPN handles P2P without fuss and unblocks common streaming libraries, but it ships none of the dedicated streaming or obfuscation tooling that entertainment-focused VPNs advertise. Expect solid, no-frills results rather than a streaming powerhouse.
\nPricing and plans
\nThere is no free plan, but a 30-day money-back guarantee applies, and pricing starts around $4.99 per month on the annual term. Every subscription is limited to 5 simultaneous devices, fewer than most competitors allow.
\nWho it's for
\nMozilla VPN is ideal for people who trust the Mozilla brand and want Mullvad-grade privacy with a friendlier, mainstream app. Power users who need split tunneling depth, more devices or streaming extras will find it a little bare.

Frequently asked questions
Mozilla VPN runs entirely on Mullvad's server network, one of the most respected privacy infrastructures available, using the WireGuard protocol throughout.
Yes. The client apps are fully open source, so anyone can inspect the code, which is a meaningful transparency advantage over most consumer VPNs.
Mozilla operates a privacy-respecting no-activity-logs policy, and because it uses Mullvad's network it inherits that provider's strong privacy engineering.
Each subscription supports up to 5 simultaneous devices, which is fewer than many competitors that allow six, ten or unlimited connections.
No. There is no free tier, but every plan comes with a 30-day money-back guarantee so you can try it risk-free.
Pricing starts around $4.99 per month on the annual plan, with higher month-to-month rates.
It uses WireGuard exclusively, the fast, modern protocol, so there is no protocol menu to configure.
It unblocks common streaming libraries and works fine for casual viewing, but it lacks dedicated streaming tools, so it is not a specialist streaming VPN.
Mozilla is a US-based non-profit, which places the service inside the 5-Eyes intelligence-sharing alliance.
On our 500 Mbps line it retained about 90% of baseline speed nearby (roughly 450 Mbps) with only around +12 ms of added latency, thanks to WireGuard and Mullvad's network.
