Mozilla has announced that it is temporarily dropping the monthly data cap on Firefox’s free built-in VPN right in time for the winter holidays. Starting November 10, anyone with access to the browser tool gets completely unlimited data through January 31, 2027.

This is actually the second time the company has pulled this move this year. We saw a very similar promotion back in June when Firefox’s built-in VPN went unlimited for the summer travel season through the end of August.

Normally, the free browser proxy caps out at 50GB of data every month before pausing your protection until the next calendar reset. Lifting that ceiling for nearly three months makes a big difference if you plan on streaming video or working remotely on sketchy airport and hotel Wi-Fi over the holidays.

In its official blog post, Mozilla said that “everyone using Firefox’s free built-in VPN gets unlimited data starting today, November 10, through January 31, 2027” so people can “browse with a little more peace of mind” while heading home to see family.

That said, it’s worth pointing out how this tool actually works under the hood compared to a full-device service like the paid Mozilla VPN. 

The free option only masks your IP address and encrypts traffic inside the Firefox browser itself, meaning other apps running on your phone or laptop stay on your regular connection. 

Mozilla also made it clear that the “VPN doesn’t make you anonymous online or hide browsing history on your device” since websites can still track you if you sign into your accounts or allow cookies.

If you are on a phone, the timing works out nicely since the built-in VPN recently rolled out to Android with Firefox 156 alongside a few media control upgrades. Desktop users can just click the shield or VPN icon in the toolbar and sign in with a Mozilla account, while Android users will find the toggle tucked inside the browser settings menu.

iOS users are still left waiting on the sidelines for now, though Mozilla says support is coming soon.

PiunikaWeb’s Take
Mozilla knows 50GB monthly is ample for casual browsing, so lifting the cap for the holidays costs little and builds goodwill. Regional availability remains the catch: despite launching in version 149, the staged rollout excludes many countries, including India, where we’re based. Plus, some users in supported regions remain in holdback studies unless they adjust data collection settings. Still, a free, uncapped browser proxy — alongside Firefox v160’s Mini Window multitasking and improved PiP controls — makes Firefox a stronger rival to Chrome and Brave.

I cover fast-moving stories across apps, online platforms, and everyday tech — phones, wearables, consoles, and whatever else people are fighting with this week. Bugs, rollouts, scams, policy enforcement, and the occasional internet-culture rabbit hole are all fair game. My goal is simple — make confusing tech news readable. When I'm not working, I'm working out or chilling with my dog. Got a tip? You can find me on X @dcubbins.
