Mozilla is providing unlimited data for its built-in Firefox VPN through January 31, 2027, removing the standard monthly cap.
Mozilla is removing the 50 GB monthly limit for its free VPN service. The company began this promotion on November 10, 2026.
The company described the change as a “gift” to users during the holiday season, PCMag reported.
Desktop and Android users in supported regions can use the unlimited data, MakeUseOf stated. Mozilla said support for iOS is coming. But the company has not confirmed a launch date.
The built-in VPN routes browser traffic through a proxy network. This masks a user’s IP address, a process that can help hide the specific sites a user visits. It works against operators of shared Wi-Fi networks in hotels or cafes, The Mozilla Blog said.
Users can pick a connection location from a list of more than 20 countries, PCMag reported. The service works within the Firefox browser only. It does not cover other applications or system-wide device traffic, MakeUseOf noted.
The VPN will not apply to the Gmail app. It also does not cover other internet-connected applications like Instagram or WhatsApp, MakeUseOf reported.
Mozilla offers a separate, paid subscription called Mozilla VPN. This service provides device-wide protection for other apps.
Mozilla’s team detailed how Firefox limits information for tracking scripts. Protections in Firefox 143 reduced the proportion of users with a unique fingerprint. In the Fingerprint Pro model, this fell from 75.7% to 46.8%.
Mozilla maintains that the free service does not compromise user privacy for the promotion.
“You’re not trading your browsing data for that protection: Firefox doesn’t sell your browsing data, interrupt you with ads, or keep a record of the websites you visit.” said Mozilla.
The VPN’s proxy infrastructure uses the content delivery network provider Fastly.
“We do not log the destinations of proxied requests. Nor do we subject proxy traffic to deep packet inspection. We do not share connection metadata with Mozilla or any third party beyond what is required for abuse prevention and network operations.” said Fastly.
The VPN does not provide total anonymity. Websites can still identify individuals through cookies. They can also identify users when a person is signed into an account, The Mozilla Blog said.
Firefox also continues to save local browsing history when using regular windows.
Users must sign in to a Mozilla account to activate the unlimited data, MakeUseOf reported.
Desktop users can access the VPN via an icon in the Firefox toolbar. Android users can find the setting through the three-dot menu under the Settings tab, The Mozilla Blog said.
Users can also configure the feature to turn on or off for specific sites, PCMag reported.
The unlimited data period ends on January 31, 2027.
