Firefox VPNs: What’s the Best VPN for Firefox?

Today, we’ll be covering the best VPN for Firefox. After all, the popular and flexible browser has many providers pitching their product as the best fit. We’ll help you separate the wheat from the chaff, and present to you the top VPN providers that work to enhance Firefox’s security and utility online.

Mozilla Firefox is a popular browser for internet users, thanks to its useful features, good security, flexibility and the ability to install add-ons to configure the browser how you want it. However, despite Firefox’s generally good security principles, there are still security risks for any web user.

Data leaks like the 2014 HeartBleed bug have gained considerable media coverage due to the leaking of thousands of personal details from various websites. There has also been an uptick in socially engineered security attacks like phishing, where scammers impersonate official sources and attempt to steal users’ passwords or other login data.

Enhance the security of Firefox with these outstanding VPNs:

  1. NordVPNBest Firefox VPN – NordVPN is the most robust privacy solution in the world, with tens of thousands of spoofable IPs and the unbreakable NordLynx protocol–all accessible from the handy Firefox extension.
  2. Surfshark – A low-cost VPN that withholds nothing from their browser extensions. Unlimited simultaneous connections, zero logs.
  3. ExpressVPN – Smart, one-click interface makes it dead simple to select the fastest VPN connection available.
  4. PureVPN – We recommend the full software rather than the trimmed down extension, as it comes with a ton of cybersecurity extras you won’t want to miss.
  5. IPVanish – A lightweight VPN that balances speed, security, and usability.
  6. VyprVPN – One of the most secure providers with their unique Chameleon protocol and self-owned network.

These issues have put security concerns at the front of many users’ minds, even if they are using a fairly solid security browser like Firefox. There are risks of identity theft or your device contacting a virus or being filled up with malware. There are also issues of privacy to consider when browsing online: who can see your internet activity, and are they recording data about you? These issues of both security and privacy are something that every internet user should be thinking about.

Today we’re going to talk about how a VPN can safeguard your privacy and security, and then we’ll share our recommendations for the best VPNs for Firefox.

How To Choose A Great VPN

From this, you can see the many reasons that someone might choose to use a VPN for their browsing with Firefox. But with so many VPN providers out there, how do you know which is the most reliable and which will best meet your needs?

When we recommend a VPN, there are four key factors that we consider:

  1. Good security. You want a VPN that offers strong 256-bit encryption to protect your data from outside observers, and you want a no logging policy to ensure that no records are kept of your internet use. This means that even if you VPN provider is forced by a government to hand over their user data, there are no records of your internet use for them to share.
  2. Fast connections. There’s nothing worse that a slow, crawling internet connection when you need to get something done online. A bad VPN can make your internet painfully slow to use, but a good VPN will have connections so fast you don’t even notice that they are there.
  3. A large server network. For maximum flexibility, you want a VPN provider that has plenty of servers available so you can always find one that works for you, plus that has servers in many different countries so that you can use these to get around regional restrictions.
  4. Easy to use software. Each VPN provider has its own software that you will use to select and connect to a server. This software should be fast, easy to use, and have useful extra features for you to get the maximum benefit from your VPN.

Top VPNs For Firefox

When we looked at all of these requirements, we came up with a list of best VPNs for Firefox:

1. NordVPN

Why Use A VPN?

What are the advantages of using a VPN in terms of security and privacy? How does a VPN help to protect you online? There are a few key issues that a VPN can help with:

Prevent your internet history being tracked

When you use an unsecured internet connection at home, it’s incredibly easy for your ISP to see every web site you visit and every file that you download. Not only can this information be used against you in legal terms – for example, if you download a copyrighted file then your ISP may alert law enforcement and send them details of your copyright infringement – but this data may also be handed over to the government so that they can track your internet use. A VPN prevents this by encrypting all of your web traffic so that your ISP can only see how much data you have transferred, not what the contents of that data is.

Block access to your device by hackers

If you use a public internet network such as the free wifi that you find at coffee shops, airports, hotels and other locations, then you are exposing yourself to a security risk if you do not encrypt your data. When multiple devices are connected to the same network, it is possible for hackers to use one device to gain access to the data being sent out from another device. This could include your personal information, credit cards details, or passwords. To protect yourself from hackers, you should always ensure that your traffic is encrypted when using a public network.

Stop your electronic communications from being recorded

Another risk of not encrypting your internet traffic is the possibility of your electronic communications being intercepted and recorded. Whether it is email, chat messages, or VoIP conversations, there is a risk that the government could snoop on your communications if they decide that you are a person of interest. To protect not only yourself but also the people whom you communicate with, you should use a VPN to encrypt your web traffic whenever you send electronic communications.

Anonymize your data when visiting websites

Many websites track information about their users, such as where in the world they are visiting from, how long they spend on the site, and how often they come back for repeat visits. If you would prefer that sites not have a complete record of every time you visit them and not have information about where you are browsing from, then you should use a VPN to prevent this information from being recorded.

Get around regional restrictions

Some internet content is only available to visitors who are browsing from a particular location. For example, video streaming websites commonly restrict access only to countries where they have the rights to broadcast that content. If you live outside these countries, you won’t be able to use the site. Using a VPN will let you get around these restrictions by making it appear as if you are browsing from the country of your choice rather than from your actual geographic location.

Avoid bandwidth throttling by your ISP

Many ISPs (including AT&T) throttle particular types of traffic, meaning that they artificially limit how much bandwidth is assigned to this traffic. For example, some ISPs throttle popular video hosting sites like YouTube because watching high definition video uses up a large amount of bandwidth. This can make it unbearably slow when you try to visit these sites or to watch video. To get around this, you can use a VPN to disguise the particular site that you are visiting, to prevent your ISP from limiting the bandwidth available for traffic to that specific site.


A VPN is an essential part of your online security, helping to keep your data private and preventing hackers from accessing your device. Users of the Firefox web browser can benefit from using a VPN to enhance their security and to protect their privacy. We’ve listed some of our favourite VPNs for Firefox and talked about the advantages of each, including those VPN providers that offer browser extensions for Firefox specifically.
