Firefox is getting a significant privacy upgrade, with parent company Mozilla announcing a free, built-in VPN as part of a wider wave of updates rolling out over the coming weeks.
The feature will debut in Firefox 149 starting March 24, embedding VPN functionality directly into the browser — no extensions or separate downloads required. Once enabled, the tool routes browser traffic through a proxy server, masking a user’s IP address and location while they browse.
“Free VPNs can sometimes mean sketchy arrangements that end up compromising your privacy, but ours is built from our data principles and commitment to be the world’s most trusted browser,” the company wrote on its blog post.

Mozilla positions the feature as a more trustworthy alternative to typical free VPN services, which it says can rely on opaque data practices. The company emphasizes that its browser-based VPN is built around its existing privacy principles, aiming to offer protection without monetizing user data.
At launch, the VPN will be available to users in the United States, United Kingdom, Germany, and France. It operates entirely within the browser, meaning it only protects traffic generated in Firefox rather than across a user’s entire device.
The VPN rollout is part of a broader push that includes new productivity tools like split-screen browsing, tab-based note-taking, and an opt-in AI assistant feature, as Mozilla looks to modernize the browser and give users more control over their experience.

Despite the added convenience, Mozilla’s built-in VPN comes with notable limitations — most significantly, a 50GB monthly data cap.
For casual use, such as checking email or browsing on public Wi-Fi, that allowance may be sufficient. But for more intensive activities like streaming video, large downloads, or extended browsing sessions, users could quickly hit the limit.
The restriction also reinforces the product’s positioning: this is a lightweight privacy tool, not a full replacement for dedicated VPN services. Power users looking for always-on protection across apps — or higher data ceilings — will still need to turn to standalone VPN providers.
In short, Mozilla’s integrated VPN lowers the barrier to entry for private browsing, but it stops short of delivering the always-on, high-capacity experience that heavier users may expect.
Users who need more data or full-device protection may want to consider standalone VPN services, which typically offer higher or unlimited bandwidth and system-wide coverage. Even many free tiers from dedicated providers provide more flexibility than a browser-only solution.
