Mozilla VPN Review 2026: Mullvad's Network, 5 Devices and a Free Rival in Firefox

Quick verdict

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.

• Good: Mullvad partnership, WireGuard only, unlimited data, kill switch that cannot be switched off, Firefox container integration.
• Weak: 5-device cap, sold in only 57 countries, refund only on your first website purchase, split tunneling missing on macOS and iOS, no ARM or router support.
• Privacy nuance: no logs of network activity, but Mozilla keeps your IP address in server logs for 90 days.
• Best for: Firefox users on Windows, Android or Ubuntu who want one account for Mozilla services and full-device protection.

What Mozilla VPN actually is

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.

Pricing and plans

There are two plans and no free tier. Both include the same features; the only difference is the billing term.

• Annual: $4.99 per month, billed as $59.88 for the year (Mozilla advertises it as saving 50%).
• Monthly: $9.99 per month.
• Every plan: up to 5 devices, 500+ servers in 30+ countries, unlimited data.
• Refund: 30-day money-back guarantee, for first-time customers only.

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.

Features: multi-hop, split tunneling and blocking

Multi-hop ("super-private mode")

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."

Split tunneling (app exclusions)

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.

Kill switch

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.

Ad, tracker and malware blocking vs custom DNS

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.

Compatibility and where you can buy it

Apps exist for Windows, macOS, Android, iOS and Linux, but the minimum versions and exclusions matter:

• Windows 10 and 11, 64-bit only.
• macOS 13 or later.
• Android 9 or later; iOS 15 or later; iPadOS 14 or later.
• Linux: Ubuntu 22.04 LTS, 24.04 LTS and 24.10 only.
• Not supported: devices with ARM processors, routers, and game consoles such as PlayStation or Xbox.

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.

Privacy, logs and audits

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.

Security audits

• 2021: Cure53 audit found two medium and one high severity issue.
• 2023: Cure53 audited the Qt6 apps on all five platforms. Findings included a WireGuard private key leaking to iCloud via keychain settings, a VPN leak through captive portal detection, and a high-severity issue where a rogue browser extension could disable the VPN. Mozilla lists all of them as addressed.
• Since then: we found no newer public audit of the Mozilla VPN apps as of September 2026.

Mozilla VPN vs Firefox's free built-in VPN

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."

• Free Firefox VPN: browser traffic only, 50 GB a month, limited locations, no cost.
• Mozilla VPN: every app on the device, unlimited data, 30+ countries, multi-hop, kill switch, up to 5 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.

Mozilla VPN vs buying Mullvad directly

Because the traffic runs through Mullvad's network, the practical comparison is with Mullvad itself (see our Mullvad review at /mullvad-review).

• Price: Mullvad charges a flat EUR 5 a month with no long-term plans; Mozilla is $4.99 a month only if you prepay a year, $9.99 month to month.
• Account: Mullvad needs no email; Mozilla VPN needs a Mozilla account.
• Data kept: Mozilla keeps IP addresses in server logs for 90 days and tracks referral data in its mobile app.
• Extras on Mozilla's side: Firefox container integration, the Windows browser extension, app-store billing and familiar payment options like PayPal and Google Pay.
• Refund: Mozilla refunds only the first website purchase within 30 days.

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.

Refunds and cancelling

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."

• Bought on the website, first time: refund of the first term; the money reaches your card in 5-10 business days.
• Bought through the App Store or Google Play: billing and refunds go to Apple or Google, and Mozilla warns these purchases "might not qualify for a refund". Google Play buyers must provide their order ID.
• Resubscribing later: no second refund.

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.

Who should buy Mozilla VPN

• Buy it if you live in a supported country, use Firefox heavily, and want a full-device VPN with an always-on kill switch on up to 5 devices.
• Skip it if you use a Mac or iPhone and need split tunneling, want to run a VPN on your router, use ARM hardware, or need more than 5 devices.
• Consider Mullvad direct if you want no email, month-to-month pricing at EUR 5, or less data kept.
• Try Firefox's free built-in VPN first if you only need browser privacy.
