Frequently Asked Questions

Do I need a VPN for Firefox?

If you ever use public Wi-Fi, want to keep your browsing away from your ISP, or need to reach content from another region, yes. Firefox's tracking protection blocks some trackers, but it doesn't encrypt your connection or change your IP. That's the gap a VPN fills.

Does Firefox have a built-in VPN?

Firefox has started rolling out a free built-in proxy in some regions, but it assigns your location automatically, caps your data, and doesn't block ads. Windscribe lets you pick from servers in 69+ countries and 135+ cities and strips out ads and trackers as you browse.

Is there a free VPN for Firefox?

Yes. Windscribe's extension is free for Firefox. You get 10 GB a month if you give us your email or 2 GB if you don't. Create an account, add the extension, and connect.

How do I add a VPN to Firefox?

Search for Windscribe on the official Firefox Add-ons store, click "Add to Firefox," and sign up. Then log in, pick a location, and connect. Full guide in our knowledge base.

Does the extension protect my whole computer?

No. It secures traffic inside Firefox only. Other apps, other browsers, games, and torrent clients aren't covered. For device-wide protection, run the Windscribe desktop app alongside the extension; they work together.

What's the best VPN for Firefox?

That depends on what you need. Ad and tracker blocking, leak protection, a no-logs policy, and a big server network are the things to weigh. Windscribe builds all of them into one lightweight extension.
