Mozilla has temporarily removed the monthly data restriction on Firefox’s built-in VPN, allowing eligible users to browse without the service’s usual 50GB allowance. The promotion began on November 10, 2026, and will remain available through January 31, 2027.
The change gives Firefox users access to unlimited browser-level VPN traffic without purchasing a subscription. Mozilla describes the temporary offer as an additional privacy benefit during the holiday season, when people frequently use the internet for shopping, travel arrangements, and other personal activities.
Firefox introduced its integrated VPN feature in March 2026, initially offering 50GB of free traffic each month. Unlike conventional VPN applications, the service operates directly within the browser and does not require users to install separate software.
The feature works by routing Firefox traffic through a proxy server, replacing the user’s public IP address with another address. This makes it more difficult for websites to determine a visitor’s approximate location or associate browsing activity with the same IP address.
It also provides additional privacy when using shared or public Wi-Fi networks. By routing browser traffic through its proxy infrastructure, Firefox can prevent local network operators from directly observing which websites users visit.
However, the built-in VPN has important limitations. Its protection applies only to traffic originating within Firefox. Other applications, including messaging services, email clients, and software running in the background, continue using their normal network connections.
Mozilla offers a separate paid product, Mozilla VPN, for users who want protection across their entire device. The standalone service covers traffic from other applications and provides unlimited data without relying on the temporary promotion.
The browser’s free VPN also does not make users anonymous. Websites can still identify visitors through account logins, cookies, and other tracking methods. Additionally, enabling the feature does not erase browsing history stored locally on a device.
Mozilla says it does not sell browsing data, inject advertisements into VPN connections, or maintain records of the websites visited through the service. The company does collect certain technical information needed to operate and monitor the feature.
Access requires a Mozilla account, and availability depends on the user’s region and the ongoing rollout. The built-in VPN is supported on Firefox for desktop and Android, while an iOS version is planned.
Eligible desktop users can activate the feature through the VPN icon in the browser toolbar. Android users can find the option in Firefox’s settings menu. The service also allows users to select from supported connection locations.
