Protection For All Your Devices


Surf in Privacy with PIA’s Firefox VPN Extension

Firefox is well-known as one of the most secure browsers available. It does offer more privacy than most, but Firefox’s protection is limited. The browser doesn’t hide your IP address, which means you can still be tracked online, and get hit with targeted ads and autofill suggestions.

In addition, Firefox can't force sites to offer secure HTTPS encrypted connections. Luckily, you can fix these issues and more by installing PIA’s Firefox VPN extension.

Compatible with: Firefox v57+

PIA’s Firefox browser extension is a VPN add-on that only covers Firefox. You’d need to install the relevant extension for other browsers if you want to secure them too. Either way, only your browser activity is protected.

On the other hand, PIA’s full-featured VPN protects your data and privacy across browsers, apps, and operating systems. We offer dedicated apps for iOS, Android, macOS, Windows, and Linux. PIA also works on smart devices, routers, Chromebook, and more.

Firefox is more private than most mainstream browsers, but it doesn’t provide complete data protection. Anyone can still stalk your online activity, harvest your browsing data, and bombard you with targeted ads — or worse.

PIA’s Firefox VPN extension prevents online tracking and those annoying ads that interrupt your browsing. Mask your IP the moment you connect to our servers and know your browsing data is wiped the second we reboot the server. No one will ever know what you’re doing online, not even us.

Just install the Firefox PIA extension, create an account, and log in. Then connect to a server to get started. We’ll encrypt your data and mask your IP address to increase your online privacy and security. You can securely access your favorite content from anywhere and enjoy ultra-fast speeds for streaming in Firefox.

If you want system-wide protection, you need the full VPN. The Firefox VPN extension is excellent if you simply want more privacy and security while browsing Firefox, but that’s all it covers.

For device-wide protection, you need PIA’s full VPN. It covers all the browsers, apps, and devices you use. Download VPN apps for Android, Windows, Linux, macOS, and iOS. PIA also supports routers, Smart TVs, and gaming consoles.

The best part is one PIA subscription gives you access to both the extension and the VPN app. You can still use the Firefox extension anytime you want to do a quick, private search.

A WebRTC leak is a common vulnerability that happens while you’re trying to establish communication using a web browser. WebRTC leaks can expose your true IP address, putting your privacy at risk.

PIA VPN masks your IP address, prevents WebRTC leaks, and provides military-grade VPN encryption to protect your data. We also provide an advanced Kill Switch that prevents any data or location leaks, even when the VPN is off. That way, your true IP address is always shielded.

PIA offers VPN extensions for Chrome and Opera, in addition to Firefox. There isn’t an extension for Safari yet, but we offer dedicated apps for iOS and macOS, so you can enjoy total privacy on all your Apple devices by installing our full VPN app.
