Most free VPNs come with a catch. They’re slow, they cap your data aggressively, or they’re funded by selling the very data you’re trying to protect. Mozilla wants to do something different. Starting March 24, Firefox built-in VPN will be available to users in the US, France, Germany, and the UK when Firefox 149 rolls out.
The feature doesn’t require any downloads or extensions. It sits right inside the browser, routes your traffic through Mozilla-managed servers, and hides your IP address while you browse. According to Mozilla, users get 50GB of monthly data at no cost. That’s considerably more than the 5GB Microsoft Edge caps its own built-in VPN at. You’ll need a Mozilla account to use it, but that’s a pretty low barrier.
What you should know before turning it on
There are a few things to keep in mind before you get excited about ditching your VPN extension. The Firefox built-in VPN only covers traffic inside the browser. Your other apps, background services, and anything outside of Firefox won’t be protected. So if you’re streaming through a separate app or syncing cloud storage, that traffic stays exposed.
It also connects to the nearest server automatically, which is good for speed but means you can’t use it to access geo-restricted content. Trying to watch something on Netflix that’s only available in another country? This won’t help with that.
Firefox already has a solid reputation for privacy, and Mozilla is clear that the browser VPN won’t log the sites you visit. Any data tied to your account gets deleted after three months. This is a separate product from the paid Mozilla VPN, which covers up to five devices system-wide. The Firefox version is browser-only and free.
Mozilla started beta testing the feature back in October 2025 with a small group of random users. The March 24 launch in Firefox 149 is when it goes wide. If you’re already using a privacy-focused browser and want a zero-friction VPN option for everyday browsing, this is worth trying out.
