Frequently asked questions
Why do I need a VPN browser extension?
Firefox is considered to be one of the best browsers for privacy and security available. However, no connection is 100% foolproof.
The ExpressVPN extension for Firefox works like a remote control for your ExpressVPN app, making it easy for you to connect, disconnect, change locations, and modify other settings right from your toolbar. But that’s not the only benefit.
The extension also offers additional privacy and security features like WebRTC blocking, beyond what any VPN can offer alone.
How do I enable VPN on Firefox?
You already get the privacy and security benefits of a VPN on Firefox if you connect to ExpressVPN on your device via the apps for Mac, Windows, and Linux. But to enjoy the added benefits of the browser extension (like WebRTC blocking and HTTPS Everywhere), follow these steps:
I got the extension. Why do I also need the app?
The extension controls and enhances your ExpressVPN app, but it is not a replacement for it. The app must be installed and running for the extension to work.
Why is a VPN extension better than a VPN browser?
The ExpressVPN browser extension is unique in that it controls the full-featured VPN app. That means all of your online activity is protected by the VPN, not just what passes through your browser.
Does a VPN hide my browser history?
Your browsing history might also be inferred by others monitoring your internet connection, such as your internet service provider or Wi-Fi operator. ExpressVPN encrypts all data between your device and the ExpressVPN servers, making it impossible for an ISP or rogue Wi-Fi to record the sites you visit.
Note that browser history is not the same as search history. If you are logged in to Google and using its search engine, those searches will be recorded even if you are using a VPN. (Learn how to delete your Google search history.)
