Firefox Begins Testing In-Browser VPN Feature to Enhance IP Protection for Paid Users

Since the first half of the year, the Mozilla Foundation has been testing a new feature called IP Protection—a concept similar to one currently under development by Google Chrome. The fundamental goal of these initiatives is to prevent websites and advertising networks from tracking users by harvesting their real IP addresses through traffic analysis.

Now, it appears that Firefox intends to elevate IP Protection into a full-fledged Firefox VPN feature. This enhancement aims to encrypt all in-browser connections through a VPN tunnel, shielding user traffic from interception while simultaneously concealing the user’s true IP address.

Firefox VPN is expected to become a premium service, available only to paid subscribers. As the feature remains in its early testing phase, pricing and data quotas have yet to be disclosed. However, it is important to note that Firefox VPN will encrypt only the traffic within the browser itself, not across the entire operating system.

Previously, the Mozilla Foundation collaborated with Mullvad VPN to launch Mozilla VPN, a service largely rebranded rather than directly operated by Mozilla. By contrast, Firefox VPN appears to be an in-house initiative—though collaboration with other VPN providers remains a possibility.

At present, the Firefox VPN infrastructure seems limited to data centers located in the United States. This means that, regardless of a user’s physical location, all traffic is routed through the U.S., potentially resulting in slower connections or limited access to region-restricted websites.

Once commercialized, Mozilla is expected to expand its global infrastructure by establishing additional data centers—at least across major international cities—to provide nearby routing options that reduce latency. Without sufficient infrastructure and performance optimization, the service may struggle to gain traction.

According to Firefox’s documentation, the browser will collect technical telemetry—including metrics such as connection quality and bandwidth usage—to improve service reliability. However, no private or sensitive user data, such as browsing history, will be collected, ensuring that privacy remains at the heart of Mozilla’s VPN initiative.
