Firefox Launches Free VPN Feature With Data Limits
With the release of Firefox 149, the company introduced a free, built-in VPN directly in the browser, eliminating the need for extensions or third-party downloads.
The feature, which began rolling out on March 24, offers up to 50GB of monthly data and is designed to protect users while they browse. Unlike traditional VPN services, this one operates only within Firefox, routing browser traffic through a proxy server to hide a user’s IP address and location.
Mozilla is positioning this as a simple, accessible option for everyday privacy. The company says the goal is to give users a quick way to stay protected when using public Wi-Fi, searching sensitive topics, or making personal purchases online. Once activated, the tool masks browsing activity by replacing the user’s IP address with one from its proxy network, making it harder for websites and third parties to track behavior.
The rollout is limited for now. Users in the United States, the United Kingdom, Germany, and France are the first to get access, with expansion expected later as Mozilla tests performance and demand. Mozilla is leaning into its reputation as a privacy-focused organization, stating that it does not sell browsing data and collects only minimal technical information needed to keep the service running smoothly.
Still, the built-in VPN has clear limitations. It only protects traffic within the Firefox browser and does not extend to other apps or system-wide activity. That means users who want full-device protection will still need a separate VPN service. Mozilla continues to offer its paid Mozilla VPN for broader coverage, which includes unlimited data and protection across multiple devices.
The 50GB monthly cap also sets boundaries on how the feature can be used. While it is enough for regular browsing, shopping, and reading, it may not support heavier activities like streaming or large downloads for extended periods. Users are notified as they approach the limit, and the VPN pauses once the cap is reached until the next billing cycle.
Security experts and early reports suggest the tool is best seen as an added layer rather than a replacement for dedicated VPN services. It can help reduce tracking and protect sessions on unsecured networks, but it lacks advanced features such as full encryption control, broader server access, and system-wide protection found in standalone VPNs.
The update also addresses dozens of security vulnerabilities, including high-severity issues tied to memory handling and browser engine flaws, signaling Mozilla’s continued focus on tightening its security posture.
