Are there limits to my Firefox Private Network connections?
With a paid subscription, the device-level protection (VPN) offers an unlimited connection for up to five devices when you connect to the Internet from any app or browser on your Windows 10 desktop. Android, iOS, Linux and macOS are coming soon.
Alternatively, the free Firefox Private Network extension is available for Firefox on MacOS, Linux and other Windows devices for a limited time each month regardless of subscription status. See the Firefox Private Network page.
