While it’s technically a private browser, Firefox is hardly different from Google Chrome when it comes to online privacy. In most cases, web browsers that are seemingly free to use still track user activity and package it into data bundles for advertisers to capitalize on. Because of this, we recommend using a VPN for guaranteed privacy. If you’re not getting a piece of that marketing pie, we see no reason to let it go unchecked.

The best VPN add-on for Firefox will hide your IP address, unblock geo-restricted content, and prevent your ISP from throttling your internet speeds. There are hundreds of free and cheap VPNs available in the Firefox Browser Add-Ons store. However, like web browsers, be wary of things that are free. We sifted through options to bring you the five Best Firefox VPN Extensions of 2021. Find the VPN that’s right for you and your browsing needs.

Ranked #1 in our book, NordVPN is the best VPN for Firefox thanks to its lightweight browser extension that doesn’t slow down connection speeds and is very easy to use. Users also enjoy NordVPN’s massive 5,500+ server network worldwide, which uses military-grade AES-256 encryption and prides itself on a verified no-logs policy.

NordVPN’s Firefox add-on also includes a built-in ad-blocker as well as a WebRTC leak blocker that protects you from security breaches while in the Firefox browser. Users should note, though, that this add-on is more of a proxy than a fully-functioning VPN app and does not protect your internet traffic outside the browser. For this, you’ll want to activate the NordVPN app. On its cheapest 3-year plan, NordVPN is an excellent choice for users with a Firefox browser.

Ultra-fast VPN great for streaming and torrenting

Visit Hotspot Shield
Cost
Lowest Price: 7.99/mo.
Speed
Avg.DL Speed: 102 Mbps
Contract
Logging: Modified "no-logs" policy
Location
Countries: 80

pros

  • One of the fastest VPNs
  • Allows torrenting & streaming
  • Free version available & free trial for premium upgrade
  • Large server network (82 countries)
  • No IP/DNS/WebRTC leaks

cons

  • As of 2020, no audits or transparency reports
  • Free version very limited on features
  • Based in privacy-unfriendly U.S. (Five Eyes)

While we rarely recommend using a free VPN if you can help it, Hotspot Shield is one provider we see value in. Hotspot Shield secures a spot on the list of top 5 Firefox VPNs for a few key reasons. Spanning 82 countries, Hotspot Shield produces some of the fastest connection speeds on the market thanks to its proprietary encryption protocol, Catapult Hydra. This makes activities like streaming and torrenting noticeably faster for its customers.

Users have the option between Hotspot Shield’s free and paid Firefox extensions. However, most users find the free Firefox add-on to be more than sufficient. It comes with an ad-blocker, cookies blocker, malware blocker, and unlimited bandwidth so your browsing is never interrupted. The one downside of this free version is that you don’t get to choose your server unless you upgrade your plan. Overall, Hotspot Shield still packs a lot into its simple Firefox extension.

Best Firefox VPN Extensions 2021 FAQs

1. How do I turn on my Firefox VPN?

You can turn your Firefox VPN on within your browser by signing into your Firefox account, navigating to your browser settings, and toggling your VPN to “Running” or “On.”

2. How do I use a VPN on Mozilla Firefox?

Similar to Microsoft Edge or Google Chrome, Mozilla Firefox allows both VPN browser extensions and VPN apps to be used on its program. Once your VPN of choice is set up in Firefox, all you need to do is make sure it’s turned on or running in the background. If that is done, you can start browsing the web with confidence knowing your data is encrypted.

3. Can I use a free VPN with Firefox?

Yes. There are hundreds of free or cheap VPNs for Firefox to choose from in the Firefox Browser Add-Ons store. However, like most things, be wary of VPNs that are free. More times than not, free VPNs don’t actually encrypt data at all, expose users via DNS, WebRTC, or IP leaks, and cause greater speed throttling than even your ISP would enforce.

If you want to avoid these potential downsides, Mozilla itself offers a Firefox VPN for just $4.99/mo. that can be used on up to 5 devices, has zero bandwidth restrictions, runs device-level encryption, and operates 280+ servers in over 30 countries.

4. How do I select the right VPN for Firefox?

When shopping for a VPN service, it’s important to look for a VPN that will hide your IP address while browsing and provide a legal workaround for accessing geo-restricted content from around the world. Additionally, you want to ensure that the VPN you use does not significantly slow down your internet speeds. Check out our top recommendations for the best VPNs for Firefox in 2021 above.

5. What is a browser extension?

A browser extension is an add-on service for your web browser that routes your browser traffic through a particular VPN server. This means that rather than using the internet unprotected, your browsing history is encrypted and your real-time location and IP address are hidden from others. 

 

Depending on which VPN extension you go with, your data may be subject to tracking anyway, so it’s a good idea to check where your VPN’s servers are physically located and what laws that country places on user data before downloading the software.

6. When do I use a browser add-on instead of a full VPN?

Generally speaking, both VPN browser extensions and full VPN apps serve the same purpose: encrypt individual data for added protection and security while using the internet. While a full VPN app is more robust than a browser extension, a simple add-on VPN is enough for users who want basic anonymity online without paying for privacy. VPN browser extensions are usually free or cheaper than VPN apps and are easier to install and use.

You can download a browser VPN add-on (i.e. extension) from your browser’s application storefront, depending on which web browser you use. Simply search for built-in VPN options in the Firefox Browser Add-Ons store, and select the VPN that best suits your browsing needs.
