Firefox's Free Built-In VPN Gets Unlimited Data From November 10 Through January 31, 2027

Mozilla has removed the data limit on the free VPN built into Firefox for the holiday season. Everyone using the built-in VPN gets unlimited data from November 10, 2026, through January 31, 2027, according to an announcement on the Mozilla blog.

The offer requires a Mozilla account. Users sign in, turn on the VPN, and browse without a data cap for the rest of the period.

What Firefox's Built-In VPN Does

The VPN routes Firefox traffic through Mozilla's service, which makes it harder for websites to use a visitor's IP address to work out their location or link their visits across sites. Mozilla says Firefox does not sell browsing data, show ads in the VPN, or keep a record of the websites users visit.

Mozilla highlights two everyday uses:

• hiding the sites you visit from whoever runs a public or shared WiFi network, such as a café or a relative's home network
• changing the location your connection appears to come from, for example to check news from home while traveling

The VPN has clear limits. It does not make users anonymous, since websites can still recognize visitors through cookies or account logins, and it does not hide browsing history stored on the device. It also covers browsing inside Firefox only. Other apps on the same computer or phone connect normally, and Mozilla points users who want device wide protection to Mozilla VPN, its separate paid subscription.

How to Turn On the Free Firefox VPN

The built-in VPN is available in Firefox on desktop and Android. Mozilla says iOS support is coming soon but has not given a date. To start using it:

1. Create a Mozilla account, or sign in to an existing one, in Firefox.
2. On desktop, select the VPN icon in the Firefox toolbar. On Android, open the three dot menu and go to Settings > VPN.
3. Follow the setup prompts and turn the VPN on.

Availability depends on the region, and Mozilla's Help Center lists the supported countries along with full setup instructions for desktop and Android.

The unlimited period lines up with holiday travel and shopping, when people spend more time on hotel, airport, and café networks. Users who already have the VPN set up do not need to do anything to get the extra data, and users who stopped using it because of the cap can turn it back on and browse for the full period without running out.

The built-in VPN is a lighter option than a full VPN app, since it protects only the browser, but it costs nothing beyond a Mozilla account. That makes it a practical choice for travelers who mainly need to protect browsing on public networks.

Mozilla has not said whether the data cap will return on February 1, 2027, or what the limit will be after the offer ends.
