How we selected and tested these VPNs

When choosing VPNs for our list, we looked at the following criteria:

  • Whether it has a Firefox add-on with good features: Indeed, the most important thing for this list is to make sure that the VPN has a dedicated Firefox extension with a range of great features to make it secure, fast, and easy to use. We chose VPNs that each had a Firefox extension that would deliver a secure and comfortable experience.
  • Speed: Delivering fast and reliable speeds are crucial for any VPN, particularly if you want to use it to stream content. After all, there are few things more annoying than dealing with buffering while you binge-watch. So we tested the speeds of the VPNs and highlighted the results in our list.
  • Whether it’s good for streaming: One of the main benefits of a VPN is that you can use it to bypass geo-restrictions on streaming services in other countries. We made sure our list included VPNs that can successfully bypass region restrictions.
  • Customer support: In case anything goes wrong, it’s important to be able to get help ASAP. Thus, we chose VPNs that offer some form of customer support to make sure you’re covered.
  • Price: When you sign up for anything, it’s vital to make sure the price is right. We chose a range of competitively priced options to suit every budget.
  • Security and privacy: One of the main reasons to use a VPN is to improve your online security and privacy. The VPNs on our list each come with a range of features to keep your information safe and secure while you’re online.

Do I really need a VPN on my Firefox browser?

Using a VPN extension on your Firefox browser is a very good idea. After all, a good one should deliver a lot of the same benefits included in a VPN desktop app, so it will improve your online security. Although it’s only a browser extension, it should still hide your IP address, and it will stop your online activity from being tracked by your ISP or other third parties. It can also allow you to unblock geo-restricted content on streaming platforms.

Some will even connect automatically, so you don’t need to remember to connect to a VPN every time you go online. And because it’s an add-on, it will likely be a more lightweight option that will consume fewer resources than the desktop app. It should also be easier to use than the app version, with fewer confusing options and features. So it can be a good choice for beginners.

Having said that, if you want to use a VPN for more than just browsing the internet, you might be better off using the desktop app. This will give you access to a lot more features. And it will deliver much more robust privacy measures. So, if protecting your online identity is a big concern of yours, we would recommend sticking with the desktop app instead.

How to set up a VPN addon on Mozilla Firefox?

Setting a VPN extension for your Firefox browser is a great step towards secure browsing. Choosing the best VPN extension for Firefox will also guarantee you the most efficient security. Thus, in this case, we would recommend NordVPN. It provides you with HTTPS to protect your traffic and it has the Threat Protection Lite feature too which blocks ads and malicious websites.

Let’s see how to set up a VPN extension on Mozilla Firefox:

  1. Download the extension from the Firefox website for extensions
  2. Click “Add to Firefox” to install the extension
Adding NordVPN extension on Firefox
  1. Click “Add” after getting prompted with permission for the extension

Is it safe to use a VPN add-on on Firefox?

Yes, so long as you’re using a reputable VPN, such as NordVPN, it’s perfectly safe to use a VPN browser extension on Firefox. A decent VPN add-on will give you some protection by keeping your online identity private, including your IP address. It will also stop hackers and other third parties from being able to track your online activity, including what websites you’re visiting and what you do while you’re on them.

Having said that, VPN browser extensions don’t have as many security features as VPN desktop apps. After all, it’s worth noting that a good VPN extension will only protect your online traffic while you’re using your browser. Some VPN browser extensions won’t encrypt your connection at all. So it’s worth bearing that in mind before you set up your add-on.

On the other hand, a VPN desktop app will protect all your internet traffic from your PC. So, provided you’ve chosen a reliable VPN, your online information will remain completely safe from prying eyes.

But it’s important to be aware that not all VPNs are as safe as they seem. In fact, some free VPN apps can actually make your data less secure.

How a VPN can help with WebRTC leaks?

A WebRTC leak is when your public IP address is exposed via the browser’s WebRTC functionality. This means that your IP address is disclosed to any site and hackers are able to access your sensitive information.

If you end up with a WebRTC leak, then getting a VPN is the best option. It is able to block any unwanted IP address leaks through WebRTC while allowing authorized connections to continue under your VPN-provided anonymous IP.

See how to check for WebRTC leak and find out if your real IP address wasn’t exposed:

  1. Disconnect and exit the VPN that you are connected to
  2. Type in “What’s my IP address” into Google to find out your original IP address and write it down
  3. Exit your browser
  4. Re-launch your VPN and refresh the webpage. Attempt step 2 once more
  5. If the displayed IP address is the same as it was before step 4, then it means a WebRTC leak is exposing your original IP address.

Can I use a free VPN for Firefox?

While it’s technically possible to use a free VPN with a Firefox extension, it’s certainly not something we’d recommend.

Free VPNs usually make money by tracking customers’ online activities and selling the information to third parties. And as if this wasn’t enough to put you off, free VPNs offer much slower speeds. And they often can’t unblock region restrictions on international streaming services.

If you really want to use a free VPN, you’d probably be better off using a freemium. This is a free version of a paid VPN that will usually have much more limited functionality than the paid-for option. They can’t unblock geo-restricted content, and they don’t offer as many security features. Freemiums also tend to come with data caps, so they’re not suitable for anything more than light web browsing.

If you do want to give it a go, however, we’d recommend trying Windscribe’s freemium option. It comes with access to a reasonable number of features, and it has a fairly high data cap of 10GB a month.

Alternatively, most paid-for VPNs offer a free 30-day money-back guarantee. So if you only want to use a VPN in the short term, you could try it out for a month and then claim your money back.


Lots of VPN services have really useful browser extensions for Firefox. They tend to be a lot more lightweight than traditional VPN desktop apps, so they come with plenty of advantages. It uses up fewer resources and offers faster connections, and it can use a different browser for regular, direct connections.

After thorough testing we can say the tools on this list will be great inside and outside of Firefox!

So if I want to be anonymous I need vpn for firefox? How is it different from guest mode? Will it save my browsing history? Thanks for helping me!! It's a difficult topic to understand
CyberNews Team
prefix 1 year ago
Hello! Here's the deal - when you use the incognito mode of a browser, your Internet Service Provider (ISP) can still see what kind of websites you've visited (even though you can't see them in your browser history). However, a VPN makes your search history unreadable to the ISP, making your internet activity truly anonymous.
