Firefox launched a free VPN service in March 2026. Over 1 million people have signed up to use it. The VPN is built directly into the Firefox browser. With the Firefox 151 update, users can now select a server from several countries: the United States, the United Kingdom, Canada, France and Germany. You can also let Firefox automatically choose the server closest to your location. The free VPN has a monthly data limit of 50GB per month. It is available on Windows 10 and 11, MacOS, Linux, Android and iOS (including iPadOS). The Firefox VPN does not rely on selling browsing data or injecting ads into traffic. This review covers the features, limitations, server selection, data cap and how it compares to other free VPN services.
How To Use Firefox Free VPN
To get the Firefox VPN, you need to install Firefox on your computer or mobile device. Then follow these steps:
- Click the VPN button at the top right of the toolbar.
- Click Get started and sign in to your Mozilla account (or create one).
- After sign in, click Turn on protection to activate the VPN.
The VPN can be turned on and off with a single click from the browser toolbar.
Server Locations And Selection
With the Firefox 151 update, you can now select a server from several countries:
- United States
- United Kingdom
- Canada
- France
- Germany
Firefox said it would be adding servers in more countries in the future. You can also choose the recommended setting, which automatically selects the server closest to your location.
Data Limit And Usage
The Firefox free VPN has a monthly data limit of 50GB per month. Here is what you can do with 50GB:
- Streaming standard definition video: about 1GB per hour (up to 50 hours)
- Streaming high definition video: about 3GB per hour (up to 16 hours)
- Streaming music: 30MB to 150MB per hour (hundreds of hours)
If you exceed the 50GB limit, the VPN will likely stop working until the next month. Paid VPNs typically have no data limits.
Privacy And Security Considerations
Firefox‘s free VPN does not rely on selling browsing data or injecting ads into traffic. However, CNET currently only recommends one free VPN service: Proton VPN‘s free tier. Free VPNs can be risky to use. Some have weak encryption, might log your activity, collect your data or could unintentionally introduce malware.
Firefox‘s VPN has a monthly data limit of 50GB. Proton VPN‘s free tier has no data limit but fewer server locations.
Shake To Summarize Feature
The Firefox 151 update added Shake to Summarize for Android devices. This feature was previously only available on iOS. When you shake your phone, Firefox will summarize the webpage you are viewing. Time magazine gave Shake to Summarize a special mention in its list of the best inventions of 2025.
Availability:
- Android: English only (more languages coming)
- iOS: English, German, French, Spanish, Portuguese, Italian and Japanese
The update also added new controls for translations and voice search on mobile devices.
