Technology reviews & practical guides
Mozilla VPN costs $4.99/mo on the annual plan and runs over WireGuard with Mullvad. We cover device limits, split tunneling gaps, 90-day IP logs, refunds and Firefox's free VPN.

Mozilla VPN is the Firefox maker's paid, full-device VPN. Under the hood it is built in partnership with Mullvad: your traffic runs over WireGuard through Mullvad's server network, while Mozilla supplies the app, the account and the billing.
That makes the review question unusual. The network is well regarded, so the real issues are price, limits and fine print - and, since March 2026, whether Firefox's own free built-in VPN already covers what you need. We checked Mozilla's pricing page, subscription terms, privacy notice and help center to find out.
Mozilla VPN is a solid, simple WireGuard VPN at $4.99 a month on the annual plan, with an always-on kill switch, multi-hop and an open-source client that ships a new release roughly every month. You pay for Mullvad's network wrapped in Mozilla's app and account.
Mozilla's subscription terms describe it plainly: "Mozilla VPN is a Virtual Private Network in partnership with Mullvad. It keeps your internet traffic private from your internet service provider by encrypting and routing it through our partner's networks instead." The features page links its server list straight to mullvad.net/servers.
The protocol is WireGuard only - Mozilla calls it "one of the most performant VPN protocols". The network is listed as "more than 500 servers in 30+ countries". Third-party sites quote larger numbers, but we stick to Mozilla's own figure.

The client itself is open source on GitHub and actively maintained: versions 2.35.0 through 2.39.0 shipped between March and July 2026, about one release a month.
There are two plans and no free tier. Both include the same features; the only difference is the billing term.
These are the USD prices Mozilla's pricing page showed on 30 September 2026. Pricing is set by country, so your local currency and amount may differ. You can pay by card, Apple Pay, Google Pay, Link or PayPal. The pricing page shows no bundle with other Mozilla services such as Firefox Relay.
The annual plan works out close to Mullvad's own flat EUR 5 per month, but the monthly plan at $9.99 is roughly double. If you do not want a year-long commitment, buying Mullvad directly is the cheaper way onto the same network.
Multi-hop routes traffic through two server locations - an entry and an exit. Mozilla's help center is honest about the cost: "your Internet speed slows down, the battery of your mobile devices may drain faster and the number of countries you can choose from may also be reduced."

You can exclude specific apps from the tunnel, but only on Windows, Android and Linux. There is no split tunneling on macOS or iOS. On Linux it also needs cgroups v1 and a GTK desktop, which rules out KDE and XFCE.

The kill switch is on by default on Windows, Android, iOS, macOS and Linux, and there is no setting to turn it off. That is safe by default, though it gives you no escape hatch if it gets in the way on a captive-portal Wi-Fi.
Mozilla VPN can block ads and ad trackers and stop downloads from known unsafe sources. These privacy features work by switching DNS servers, so they cannot run at the same time as a custom DNS server of your own. Pick one or the other.

Apps exist for Windows, macOS, Android, iOS and Linux, but the minimum versions and exclusions matter:
No router support means you cannot stretch the 5-device limit by protecting a whole home network, which many rivals allow.
Availability is the other catch. Mozilla's terms list 57 countries where you can subscribe, including the US, UK, Canada, most of the EU, India, Singapore and Australia. In 24 of them - among them Australia, India, Brazil, Mexico, South Korea and Taiwan - you can only buy through the mobile apps, and in Bangladesh, Brazil, Morocco and Senegal only on Android. Mozilla also states the service will not work if your connection originates in mainland China.
Mozilla's privacy notice says: "No logs of your network activity are maintained by either Mozilla nor our partner Mullvad when you're using the Mozilla VPN service in any circumstance." That covers what you browse and connect to.
It is not zero data, though. Your IP address "is collected as part of our servers logs for 90 days", which Mozilla uses to approximate your location for availability and pricing and to prevent fraud. The pricing page FAQ also says Mozilla tracks "campaign and referral data" in the mobile app. You also need a Mozilla account with an email address, unlike Mullvad's anonymous account numbers.
Starting with Firefox 149 in March 2026, Firefox ships a free built-in VPN with 50 GB of browsing per month. It is a different product: a proxy that replaces your IP address inside the browser only. It began as a beta for desktop users in the US, UK, Germany and France, gained location choice (US, UK, France, Germany, Canada) in May, and started rolling out to Firefox for Android in July.

Mozilla itself draws the line: the free VPN "does not offer full device protection ... The standalone Mozilla VPN subscription offers this capability with unlimited data across multiple devices."
If you only want to hide your IP while browsing on public Wi-Fi, the free feature may be enough. If you need your email client, games, torrents or other apps covered, you need the paid VPN.
Because the traffic runs through Mullvad's network, the practical comparison is with Mullvad itself (see our Mullvad review at /mullvad-review).
For privacy-first users, Mullvad direct is the cleaner deal. Mozilla VPN makes more sense if you value the Mozilla account, Firefox integrations, or paying through Apple or Google.
The 30-day guarantee is narrow. Mozilla's terms say: "The first time you subscribe to the Services through Mozilla's website, if you cancel your account within the first 30 days, you may request a refund ... This offer only applies the first time you subscribe."
To cancel, use the Cancel Subscription link in any Mozilla VPN email or the Subscriptions & Payments section of your Mozilla account; in the app it is Settings > Account > Manage subscription. Access continues until the end of the current billing cycle.
$4.99 a month on the annual plan ($59.88 billed yearly) or $9.99 on the monthly plan, as shown in USD on 30 September 2026. Prices vary by country.
It runs on Mullvad's network, but it is sold and managed by Mozilla. You get Mozilla's app, account and billing, while traffic is encrypted with WireGuard and routed through Mullvad's servers.
Up to 5 devices per subscription. Routers and game consoles are not supported, so you cannot cover extra devices through your home network.
It keeps no logs of your network activity. Mozilla does store your IP address in server logs for 90 days for location, pricing and fraud checks.
Only on your first subscription bought through Mozilla's website, if you cancel within 30 days. App Store and Google Play purchases are handled by Apple or Google and may not qualify.
No. The free Firefox VPN protects browser traffic only, with 50 GB a month. Mozilla VPN covers every app on the device with unlimited data.
Yes, on macOS 13+ and iOS 15+, but split tunneling is not available on either, and the kill switch is always on.

Browse Virtual Private NetworkWith Firefox Multi-Account Containers you can give each container its own VPN location, or exclude a container entirely by pointing it at the proxy socks://localhost:3182. A separate Mozilla VPN extension for Firefox, launched in March 2025, adds per-website VPN rules - but it is Windows only.
