SNACK: 3-line summary
- Mozilla is temporarily removing the data cap on Firefox’s built-in VPN through January 31, 2027
- Eligible desktop and Android users must sign in with a Mozilla account; iOS support is still to come
- The feature covers Firefox browsing, not other apps, and does not make you anonymous online
Firefox’s free built-in VPN is getting a temporary break from its data cap. Mozilla announced on November 10 that unlimited data will be available through January 31, 2027, replacing the usual 50 GB monthly allowance for the period. This is not a price change for Mozilla VPN, the separate paid service.
Availability still depends on your region and rollout
The announcement covers Firefox on desktop and Android. You need to sign in with a Mozilla account and turn on the VPN. Mozilla says iOS support is coming soon, rather than available at launch.
South Korea and Japan are on Mozilla’s current availability list. Even in a supported region, the feature may not appear for every account yet because it is rolling out in stages. The help page also says remote improvements must be enabled, and enterprise policies can restrict availability.
Start in the toolbar or Android settings
On desktop, select the VPN icon in the Firefox toolbar to begin setup. On Android, open the three-dot menu and go to Settings > VPN. Follow the account sign-in and setup prompts, then turn on the VPN.
Unlimited data is not complete anonymity
The built-in feature covers browsing within Firefox. It does not protect traffic from your email client, messaging apps or other apps on the same device. Mozilla distinguishes it from the separate, paid Mozilla VPN service for device-wide protection.
Websites can still recognize you through cookies or an account you sign in to, and the VPN does not hide browsing history stored on your device. The temporary removal of a data cap does not remove those limits.
A word from the Snackgirls
AIKO The data cap gets a holiday. Cookies still report for duty. A VPN and a signed-in account are separate matters.
Nea I’d like to look through the setup screen. I wouldn’t want to mistake it for protection for every app.
