Mozilla removes data cap for Firefox built-in VPN until January 2027

Mozilla has announced a temporary removal of the 50GB monthly data cap for the built-in VPN feature within the Firefox browser. This change, which went into effect on 10 November 2026, allows users to browse without a fixed data limit until 31 January 2027.

To access this unlimited data tier, users must be signed in with a Mozilla account. The service functions as a browser-level proxy rather than a system-wide VPN, meaning it only masks traffic generated within the Firefox application itself.

Firefox VPN service details

• Service Scope: The built-in VPN is a browser-level tool that masks activity only within Firefox, unlike the standalone Mozilla VPN which secures all desktop and system services.
• Usage Requirements: Accessing the service requires a Mozilla account login and supports private browsing mode.
• Configuration Options: Users can implement per-site exceptions to prevent specific websites from being routed through the VPN proxy.
• Policy Timeline: The unlimited data promotion is scheduled to expire on 1 February 2027, at which point the 50GB monthly limit will be reinstated.

Why it matters

While this provides a temporary benefit for privacy-conscious users on data-constrained connections, it does not offer the full system-wide encryption required for securing all Linux desktop traffic. Users requiring comprehensive network security for non-browser applications will still need to rely on system-level VPN solutions.
