Best VPN for Firefox

Best VPN for Firefox 2021

Last updated on December 23, 2020

Firefox is one of the most popular internet browsers out there. It has been used for years by millions of people worldwide to access online content quickly and easily. One of its most attractive features is that it is reliable and allows for a number of extensions.

Here, we investigate using a Firefox VPN browser extension to up the ante in terms of online security for you and your family or business as well as looking at how a VPN for Firefox can be used to open up a whole host of restricted content.

We recommend ExpressVPN’s Firefox VPN browser extension.

Why Do You Need A VPN For Firefox?

We advocate using a Firefox VPN extension as it allows internet browsing sessions to become private and anonymous – even when using a public wifi network. We should all do more to improve our online safety with the rise of cyber criminals and hackers as well as the increase in state intervention in our use of the internet online. It is not uncommon for governments to spy on its citizens through their internet activity.

Using a VPN for Firefox is a method of making all online sessions private as a VPN makes connections untraceable and impregnable by encrypting all data that is transmitted. This is made possible by a VPN provider giving you another server to connect to the internet through. This connection not only gives you a new IP address, thus hiding your location, but it also hides your personal details while encoding your online usage.

The fact that VPN users gain a new IP address, or at least the appearance of one, is important as it means that users can then access blocked content that has been restricted for geographical reasons. Frequent travellers will know that they cannot always access the shows they once did on Netflix if they are out of their native country. Citizens of stricter countries, where pornography or other content is deemed illegal, will have experienced the inability to access some sites that citizens of more liberal countries can view freely. A VPN is a way to open up such content wherever you are.

All this adds up to a convincing argument for why we should all have a VPN and use a Firefox VPN browser extension if that is the internet browser we use.

What Makes The Best Firefox VPN Extension?

Before choosing a suitable VPN for Firefox that fulfils your needs either as an individual, household or business, it is good to know what makes the best VPN for Firefox. If a VPN provider does not have a number of fundamental features, they are not worth using – whether you have downloaded a free one or subscribed to a service.

Here are the four features that we required to see to make it onto our list of recommended Firefox VPN browser extensions.


  • Military Grade Encryption Techniques – Without using the most strongest encryption techniques, VPNs can still be hacked to reveal a user’s identity, online activity and other important personal details. We therefore like to see AES-256 encryption keys as standard. This encryption method is used by the US Government for its own online activity and is amongst the best method of upholding user anonymity.


  • Vast Network of Servers – If you are going to find a VPN useful, it absolutely has to be provided by a company that has a large number of servers available. Not only does this guarantee a connection whenever and wherever you need, it also means that customers can be assured that their connection will be quick. This means that they will always have a freeze free internet browsing session, which other less reputable VPN browsers may yield.


  • Many Server Locations – If you are particularly concerned with accessing online information from around the globe, that may otherwise be blocked due to the aforementioned geographical restrictions (government implemented or not), you need to subscribe to a VPN browser service that has a large number of country locations for its servers. It is this way that they are able to provide the IP addresses that allow access to that very geo-blocked content.


  • Anonymity and Privacy – One of the main reasons that people use a Firefox VPN extension is to maintain their privacy so they cannot be spied on or have their systems hacked. However, while some VPN providers do increase customer online security, they have lacks rules around what they do with the data that they themselves can record from their customers’ online usage. In short, they can keep logs of all its users and what they get up to online. We like to see a secure Firefox VPN that is provided by a company that maintains a no logs policy so that information can never be given over to any third parties, for whatever reasons.

Can I Use A Free VPN For Firefox?

A free VPN for Firefox may be tempting but it should never be a temptation worth acting on. We simply don’t believe it to be worth the risk to your online safety given the level of service that free VPN browser providers can offer. To be able to provide a service for free, companies have to make savings elsewhere to remain profitable. They often do this using the following methods


  • Limiting bandwidth – A free VPN for Firefox usually only ever provides a certain amount of data each month for a customer to use. This is ordinarily so low that customers use it up within days so that they can no longer access the internet or stream videos in a manner that is at all pleasurable or safe.
  • Weak encryption techniques – Excellent encryption techniques do not come cheap so free VPN for Firefox providers often only have the weakest of encoding devices and methods. This means that customers who use such browser extensions for Firefox are still easy to trace or still easy to hack.
  • Keeping logs – In conjunction with having weak security methods in place, many of the popular free VPN providers maintain logs of their user online activity, often to sell on to the highest bidder.
  • Unreliable connections –  Free VPN for Firefox users often experience internet browsing sessions that are buffered or prone to freezing owing to the unreliable connections that their providers can offer. It makes them almost unusable.


How To Choose A Secure Firefox VPN – The Bottom Line

We always advocate using ExpressVPN as a Firefox VPN extension. Not only is it reliable and consistent in terms of connection, the security it gives to its users whilst they are online is second to none. These concerns are paramount when choosing a secure Firefox VPN and ExpressVPN answers them easily whilst also providing excellent customer service as well as an easy to use application.

We’re confident that customers never have to make use of its 30 day money back guarantee policy.
