Mozilla has officially revealed that it will provide a built-in and free VPN service for its popular web browser, Firefox, later this month. This new feature will be rolled out with the Firefox 149 update on March 24, 2026. Users will be granted a generous 50 GB monthly data cap, which is notably high for a browser-based service.
To benefit from this service, users will need to create a free Mozilla account. Initially, the service will be available to users located in the United States, France, Germany, and the United Kingdom.
50 GB of Free Data with Firefox 149
It is important to note that this integrated feature does not protect the entire device’s internet traffic. Instead, it functions as a browser-level proxy, securing only the data flow within Firefox and not interfering with other applications on the device. Furthermore, it does not include advanced VPN features such as manual server switching to bypass geo-restrictions or access streaming platforms.
Highlighting the security concerns seen with third-party extensions in other browsers, Mozilla emphasizes that its system is built strictly on data privacy principles. The service works via a proxy to mask your IP address and location while browsing.
Strategic Move to Reclaim Market Share
While Mozilla already offers a paid VPN service utilizing the Mullvad infrastructure, this new free version will instead utilize Mozilla’s own global server network, as indicated by beta tests conducted in late 2025. Similar to the Proton VPN integration in Vivaldi, this move aims to attract users and eventually guide them toward the fully-featured, paid Mozilla VPN subscription.
Over the past year, Firefox’s desktop market share has declined from 6.3% to 4.2%. By deploying this VPN service alongside upcoming features like an AI-assisted browsing mode, the company aims to preserve user goodwill and reverse the downward trend in its market share.
As privacy concerns grow in the digital world, built-in security tools provided by browsers are becoming increasingly vital. What are your thoughts on these integrated free VPN services? Which browser do you trust to protect your data during daily use? Share your views in the comments!
