Firefox Makes Its Free Built-In VPN Unlimited Until 31 August
Mozilla has temporarily removed Firefox’s normal 50GB monthly VPN limit. This page focuses only on the offer: who receives it, what it protects, which locations are available and what changes on 1 September.
The important distinction is simple: “unlimited” refers to Firefox browser bandwidth during the promotion. The feature remains browser-only and does not become a whole-device VPN.
What Has Mozilla Changed?
Firefox’s free built-in VPN normally gives eligible users 50GB of protected Firefox browsing each calendar month. Mozilla has temporarily removed that limit and expanded location choice for the summer period.
| Feature | Normal Offering | Temporary Summer Offering |
|---|---|---|
| Monthly bandwidth | 50GB per calendar month. | Unlimited through 31 August 2026. |
| Location choice | Five standard country options. | Mozilla advertises 28 country locations. |
| Price | Free for eligible users. | Still free; no subscription upgrade is required. |
| Protection scope | Firefox browser traffic only. | Unchanged: Firefox browser traffic only. |
| Account requirement | Mozilla account sign-in required. | Unchanged. |
What happens on 1 September?
Mozilla says the built-in VPN will automatically return to its normal 50GB monthly allowance and five-location set. Users do not need to cancel anything, and the temporary upgrade does not become a paid subscription.
Who Is Eligible?
The upgrade applies automatically to eligible users who already have access to Firefox’s built-in VPN. Mozilla is introducing the feature gradually, so living in a supported country does not guarantee that the VPN icon has reached a particular account or installation.
Mozilla’s current support page lists availability across 26 countries. The feature began its staged rollout with Firefox 149. A Mozilla account is required, and enterprise environments managed through Firefox enterprise policies are excluded from the normal rollout.
Mozilla says eligible users receive the unlimited allowance and expanded locations automatically. There is no promotional code, payment step or separate extension to install.
Why might the VPN be missing?
- The staged rollout has not reached the user yet.
- The user is outside a currently supported region.
- Firefox is not on a supported current release.
- The installation is managed by enterprise policy.
- The VPN icon was previously removed from the toolbar.
- The user is not signed in to a Mozilla account.
How to Enable Firefox’s Built-In VPN
- Update Firefox to the latest available version.
- Look for the VPN icon or setup invitation in the Firefox toolbar.
- Select Get started.
- Sign in to an existing Mozilla account or create one.
- Open the VPN panel and use the switch to turn the feature on.
- Select Recommended for an automatically chosen route, or choose an available country manually.
When enabled, Firefox routes supported browser traffic through the proxy service. Websites then see the proxy address rather than the user’s normal public IP address.
What Does the Free Firefox VPN Protect?
Mozilla describes the feature as a secure proxy that conceals the user’s IP address for Firefox browsing. It can reduce what the local network and internet provider can infer from direct connections and can prevent websites from seeing the user’s normal public IP address.
| Activity | Protected by Firefox Built-In VPN? | Important Detail |
|---|---|---|
| Websites opened in Firefox | Yes, normally | The site sees the proxy IP unless it is excluded or the VPN is disabled. |
| Firefox webmail | Yes | The browser connection is routed, but the email account still identifies the user. |
| Downloads started in Firefox | Normally | Protection depends on the download continuing through Firefox rather than another application. |
| Firefox tabs opened before activation | New network requests are routed while enabled | Already loaded content and existing account sessions remain unchanged. |
Logged-in accounts, cookies, browser fingerprinting, payment information, website permissions and information typed into a site can still identify a user. A changed IP address is only one part of online privacy.
What Does It Not Protect?
- Other browsers: Chrome, Edge, Safari, Brave and browser traffic outside Firefox do not use it.
- Email applications: Outlook, Apple Mail, Thunderbird and mobile email apps are outside the Firefox tunnel.
- Games and launchers: Steam, Epic Games, consoles and native game traffic are not protected.
- Torrent applications: BitTorrent clients do not use the browser-level service.
- Video-call applications: Zoom, Teams, Discord and native calling applications remain outside it.
- Operating-system services: updates, background sync, telemetry and other system traffic are not covered.
- Other devices: phones, televisions and consoles on the same network do not inherit protection.
- Precise location: websites can still receive GPS or other location data if the user grants permission.
Firefox’s built-in VPN is a browser-level IP-protection service. Its unlimited allowance applies only to supported traffic inside Firefox.
Which Locations Are Available?
Mozilla’s summer announcement says users can choose from 28 country locations. However, the country list published in that announcement and the current support page names the following 26 countries:
Mozilla has not explained on the cited pages why its headline says 28 country locations while the published list names 26 countries. The difference may involve multiple locations within a country or an incomplete list, but that should not be assumed without clarification.
Choosing a country changes the IP location websites see. It does not automatically change account country, payment region, GPS location, language settings or every service’s licensing decision.
What Data Does Mozilla Say It Collects?
Mozilla’s support documentation says it processes technical and interaction data needed to operate and improve the feature. Examples include connection success or failure, device and operating-system information and the amount of data used on a particular day.
Mozilla says the VPN does not log the websites users visit or the content of their communications. Its Firefox Privacy Notice says the proxy server is operated on Mozilla’s behalf and does not collect the websites visited or the content of those sites.
| Data Type | Mozilla’s Published Position |
|---|---|
| Websites visited | Mozilla says the VPN does not log them. |
| Page content, messages or passwords | Mozilla says the proxy does not have access to this sensitive content. |
| Connection status | Technical connection-success and failure data may be processed. |
| Usage volume | Mozilla may record that a quantity of data was used on a particular day. |
| Device and browser details | Client version, device type and operating-system information may be processed. |
| Mozilla account information | Account sign-in is required and is governed by Mozilla’s account privacy terms. |
Can You Turn the VPN Off for One Website?
Yes. Firefox allows users to disable VPN routing for the current website or add sites to an exception list in the browser’s privacy and security settings.
This can help when a bank, streaming site, workplace portal or other service blocks the proxy address, shows repeated verification challenges or loads incorrectly.
A website on the exception list connects without the Firefox VPN. The site and local network can therefore see the normal connection information that the VPN would otherwise conceal.
Mozilla also excludes some essential Mozilla services from VPN routing so account sign-in, reconnection and public Wi-Fi captive portals can work.
Important Limitations
- Temporary offer: unlimited usage ends automatically after 31 August 2026.
- Browser-only: no protection for apps or operating-system traffic.
- Progressive rollout: some eligible users may not yet have the feature.
- Mozilla account required: it is not an account-free or anonymous service.
- Website blocking: some services may reject or challenge proxy addresses.
- No anonymity guarantee: accounts, cookies and fingerprinting can still identify users.
- Country-list discrepancy: Mozilla advertises 28 country locations but currently names 26 countries.
- Enterprise exclusion: managed Firefox environments are outside the standard rollout.
- No device sharing: the feature does not protect a hotspot, router or other devices.
Is Firefox’s Unlimited Free VPN Worth Using?
You want a simple, free way to mask Firefox’s public IP address without worrying about the normal 50GB limit until 31 August.
The feature still covers supported Firefox traffic only, still requires a Mozilla account and returns to the normal allowance on 1 September.
The temporary upgrade is a meaningful improvement to Firefox’s free privacy feature. Unlimited bandwidth applies only to supported Firefox browser traffic and ends on 31 August.
