Why should you use a Firefox VPN?

A Firefox VPN extension lives inside the browser, encrypting all requests and traffic generating from it. There are many kinds of viruses that specifically target vulnerabilities in the browsers themselves. A VPN extension can help enhance the security of your Firefox browser.

VPN extensions also come in handy when you frequently visit websites that might be blocked on your country’s regular Internet. A stand-alone VPN client is more resource-intensive and might slow down your computer.

However, Firefox VPN extensions are lightweight and ideal for users that only want to tunnel their browser data rather than the entire traffic being generated on the computer.

What is a VPN Add-on?

A VPN addon is an extension that VPN providers offer. Addons are similar to VPNs offering the same benefits and services as a full VPN. Think of VPN addons as a lighter or mini version of a VPN. Some of the VPN providers mentioned above offer standalone VPN addons.

One of the main reasons people use a VPN add-on is that they are lighter and faster than a full VPN. But despite that, VPN add-ons let you access geo-restricted content with ease.

Firefox VPN Addon VS. Stand Alone VPN App

VPN addons for Firefox and other web browsers work best when you intend to browse the Internet and access streams with fast speed. Some of the providers listed above offer a browser VPN add-on, also called a proxy extension. These add-ons are lightweight because they use fewer resources as compared to a standalone app.

However, these VPN addons for Firefox and other browsers come at the expense of privacy and security. These browser add-ons cannot affect other programs and services on your devices communicating with the Internet, but browser add-ons are much less secure than full VPN clients.

Therefore, if your priority is fast browsing and streaming through sites, then a Firefox VPN extension is your best bet. However, if you are thinking more from the point of view of security and encryption and want to protect all your traffic, you should aim for a stand-alone VPN client.

WebRTC Leak Protection

WebRTC, otherwise known as Web Real-Time Communication, is a built-in program that allows browser-to-browser communication through audio, video, and data transfer. This program can be found in many browsers, including Firefox, Chrome, and Opera. In short, WebRTC poses a risk for VPN users because it might leak their real IP address. Therefore, top-of-the-market VPN providers offer WebRTC leak protection to their users.

It might not be an issue if you are using a VPN app, but you need to be careful about WebRTC leaks with a VPN addon. Without WebRTC leak protection, you will end up exposing your real IP address, even if you are using a VPN.

Among the VPN providers mentioned above, the PureVPN addon comes with WebRTC leak protection by default. Meaning, with the PureVPN add-on, you don’t have to configure the settings manually, as it is already built-in.

Even with other VPN browser extensions, you can disable WebRTC. To do that, Open the Firefox browser, enter about:config in the Firefox browser address bar. It will take you to a window displaying a warning message about changing the settings. To disable WebRTC click on Accept the Risk and Continue.


Now, in the search bar, enter media.peer connection.enabled. In the column below, if it says false, then it means WebRTC is disabled. If it says true, then click the chrome://browser/skin/toggle.svg button to disable WebRTC. And you are good to go!  


Best free VPNs for Firefox?

In my opinion, free VPNs are a big no. When it comes to using a VPN for a web browser like Firefox, most online users go for the free ones since these are readily available on the internet.

However, most free VPNs may sell your data over to third-parties for some money, while others would only attract the consumer to purchase their premium version.

Not only that, most free VPNs don’t actually offer extensions for Firefox browsers. This is exactly why I highly suggest using paid VPNs that offer reliable extensions for Firefox to secure your privacy.

However, if you are still looking for a free VPN for Firefox, we have listed down two free VPNs better than other VPNs. But, keep in mind that with free VPNs, you will have to compromise on some privacy.

1. Hotspot Shield

Hotspot Shield is an excellent choice if you need a free VPN for Firefox. You can pay for a subscription or use Hotspot Shield for Firefox for free with a bandwidth of under 500MB per day at 2 Mbps.

It offers multiple servers in 80+ locations. Also, the Hotspot Shield Free only gives access to the US server location and is supported by ads. It will work with Firefox, but if you stream video content, you will face issues.

2. ProtonVPN

ProtonVPN is another free Firefox VPN. ProtonVPN Free offers unlimited bandwidth and can also unblock US Netflix. There is no data restriction, so with ProtonVPN Free, you can browse on Firefox as much as you want.

However, it only offers three locations (US, Japan, and the Netherlands), and you can only connect one device at a time. This Firefox VPN plugin is also very slow in case you want to use it for streaming.


Let’s take a look at some of the common frequently asked questions.

Does Firefox Support VPNs?

Yes, Firefox does support VPNs – both VPN apps and VPN addons for Firefox.

Is Firefox VPN any good?

Firefox’s VPN, called Mozilla VPN, is good even though it is still in its early stages. It is a low-cost VPN with high performance. However, it lacks some features that are available in other popular VPNs like PureVPN and ExpressVPN. Also, it cannot unblock most streaming sites. So, it would be best if you stuck to one of the providers mentioned above for maximum security and performance for the moment.

How do you add a VPN to Firefox?

To add a VPN to Firefox, follow these steps:

  1. Go to the Firefox Add-ons page and look for your VPN.
  2. Click Add to Firefox and wait for the VPN to be installed.
  3. After the installation is complete, the VPN icon will appear at the top right corner of the Firefox browser.
  4. Click on the VPN icon, log in with your details, and that’s it!

Wrapping Up!

With the growing number of browser-based vulnerabilities, geo-restrictions, online tracking, you never be too safe online.

Even though Firefox is much more secure than Chrome, using the best VPN for Firefox is always a smart choice.
