Best VPN service for Firefox (with add-ons or browser support)

If you use Mozilla Firefox and are looking for a VPN, you’ll find the best provider that specializes in your unique requirements. Numerous providers provide specialized Firefox add-ons that give a more lightweight solution for masking your IP while you surf.

A VPN encrypts and tunnels your traffic via an intermediate server located in the location of your choosing. It replaces your IP address with one from the location you choose. This ensures that no one can track your behavior and that you may safely access geo-restricted websites and applications.

Using a browser add-on—also known as an extension—normally does not provide the same level of protection as a complete VPN and is not recommended in all circumstances. This is why many VPN companies include them as part of their standard offering.

Indeed, we advocate subscribing to a comprehensive VPN service that includes desktop software, mobile apps, and Firefox VPN add-ons that you can use across many devices and browsers as required. VPNs are reasonably affordable and require little technical expertise to set up.

Best VPN for Firefox

To assist you in making your choice, we’ve suggested the top VPN for Firefox users using the following criteria:

  • Includes a Firefox add-on or specific support for Firefox.
  • Connects users in a timely and secure manner.
  • Can access well-known streaming websites.
  • Provides substantial security.
  • Has a policy against logging.

NordVPN

NordVPN has a network of over 5,000 servers in several different countries. Its Firefox extension may be used independently from the app. As a result, it provides a more lightweight option to using a complete VPN service. Additionally, unlike many proxy extensions, NordVPN promises that its Firefox add-on encrypts communications and protects against IP leaks.

The add-on settings may be customized to automatically connect when the Firefox browser is opened. A clever CyberSec function prevents your device from being infected by malware and other risks by blocking questionable websites.

NordVPN is a popular choice for streamers. The VPN service boasts some impressive speeds and is compatible with popular streaming services such as US Netflix, Amazon Prime, BBC iPlayer, HBO, and Hulu.

This provider’s rigorous no-logs policy makes it suitable for privacy-conscious users. DNS leak prevention and a built-in kill switch guarantee that your IP address will never be exposed inside the main VPN client. Military-grade 256-bit encryption ensures security.

The entry-level NordVPN plan lets you connect to up to multiple devices concurrently. If you alternate between Firefox and Chrome, you’re in luck, since a Chrome extension is also available. Please keep in mind that the Firefox extension for Android has not been thoroughly tested, and users may encounter bugs.

There are VPN client applications available for Windows, Mac OS X, iOS, Linux, and Android.

How to configure a VPN connection in Mozilla Firefox

Once you’ve selected a VPN service from the list above, just follow the instructions below to safely access the internet using your VPN. In the next section, we’ll discuss why it’s better to use the complete VPN program rather than just the browser extension.

  1. Choose a VPN company that prioritizes security and privacy. NordVPN is recommended.
  2. Then, either visit the VPN company’s website and download the VPN program that is compatible with your device, or go to addons.mozilla.org and search for your VPN provider.
  3. Permissions must be granted and the app or browser extension must be installed.
  4. Choose a server for privacy purposes. Any server is fine. However, if you would like to securely access geo-blocked services while traveling abroad, make sure to select a server in a country where the content is not restricted.
  5. Allow for connection establishment before clearing your cache and cookies.
  6. You should now be able to surf the internet anonymously using Firefox!

How we selected the best VPN for Firefox

There are numerous critical factors to consider while selecting a VPN, particularly if you want to keep your internet activity hidden. We used the following criteria to exclude providers that were not up to the job, leaving just the top VPN for Firefox:

  • Performance: Regardless of the work at hand, you can be certain that sluggish speeds will create issues. As a result, we decided to suggest only a VPN with fast speeds and stable connections.
  • Versatility: To make sure that your VPN can handle anything you throw at it, we searched for those that were well-suited for torrenting, surfing, gaming, and streaming. This includes evaluating their ability to safely access platforms such as Netflix, Disney Plus, and Amazon Prime Video while traveling.
  • Security toolkit: VPNs are usually used to protect your surfing activity from prying eyes. That is why we only advocate for a provider with a “no-logs” policy. Additionally, we ensure that our top provider browser extension has at least 128-bit encryption, leak prevention, and a kill button.
  • Ease of use: The more user-friendly a service is, the better. We sought out VPNs that offered specific Firefox extensions, as well as robust cross-platform support, live chat, and user-friendly applications. Bonus points if they used servers designed for certain jobs, cut connection constraints completely, or offered 24/7 support.

When should you use a browser add-on rather than a complete VPN?

You may use a standalone add-on, also known as an extension or proxy extension, with the provider indicated above. One of the primary benefits of using an add-on rather than a VPN software is that the add-on consumes less resources owing to its lightweight design.

Having said that, this is often at the price of security. Numerous extensions will disguise your IP address, preventing your ISP from logging your activities. However, it does not encrypt your transmission, leaving your data vulnerable.

Certain add-ons, such as the one included with the NordVPN bundle, encrypt your traffic. However, it’s important to keep in mind that this only pertains to the browser you’re currently using. This will not safeguard any other browsers or programs on the device.

Additionally, the NordVPN add-on secures access to all websites, even those that are not HTTPS, and protects against DNS leaks. Again, these are not standard VPN browser extension functions.

What, then, should you use? Simply defined, an add-on is acceptable in instances when speed is critical, such as general surfing or streaming. However, if security and privacy are critical, you’re better off utilizing the VPN app. The lone notable exception is the NordVPN extension, which does provide a greater degree of protection than the rest.

Using a VPN with Firefox: FAQs

Is it possible to use a free VPN with Firefox?

The VPN plans reviewed here are the most affordable options available to Firefox users. While browsing providers, you’re likely to come across a plethora of free options, some of which may include specialized Firefox add-ons. There is a lot to be said about receiving anything for free these days, which is why you must exercise caution while using these services.

Some are just lacking features. They may, for example, have poor speeds, a limited number of servers, and low data limits. Many provide severely restricted service in the expectation that you’ll ultimately pay for a premium plan.

Others earn money from users in more unethical ways. These include monitoring user activities, activating tracking cookies, and displaying obnoxious affiliate advertisements. Because paid plans are often more affordable, they’re definitely your best bet.

What does WebRTC blocking entail?

Web Real-Time Communication (WebRTC) is a protocol that enables some types of browser-to-browser transmission, most notably audio and video communication. It is integrated into a lot of browsers, including Firefox, Chrome, and Opera. WebRTC presents a danger to VPN users by exposing their true IP address. As a result, several providers provide WebRTC leak prevention as a basic feature.

Even when this is the case, it does not always apply to add-ons, therefore it is worth noting. Essentially, if you allow WebRTC but do not activate WebRTC leak prevention, you risk revealing your actual IP address to the websites you visit, even if you are using a VPN.

NordVPN is the only provider on our list that offers a standalone add-on that protects against WebRTC leaks. ExpressVPN’s add-on works in conjunction with VPN software, so you’ll benefit from WebRTC leak prevention from both.

Even with the other additions, there is a rather straightforward fix. All that is required is to deactivate WebRTC. To begin with, type about:config into the address bar of your Firefox browser. You’ll get a warning about the dangers of modifying advanced settings. If you’re OK with proceeding, click “I accept the risk!”

Enter media.peerconnection.enabled in the search field on the following screen. If the Value column has a value that is false, WebRTC has already been deactivated. If it says “true,” you must double-click the column to alter it to false.

That is all. You can verify whether your IP address was revealed by using a leak tester such as the DNS leak test tool.

Keep in mind that even with WebRTC deactivated, you may have trouble while attempting to utilize specific programs that depend on it. If you need to re-enable it, just repeat the preceding steps and set the value to true.
