One way to up your internet’s privacy and security is by installing a quality VPN for your Firefox.

Advantages of Using Firefox VPN

  • They are free or much cheaper than VPN apps
  • Easy installation and user-friendly setup

Disadvantages of Using Firefox VPN

  • VPN browser extensions are merely proxy servers and most of them do not encrypt your data
  • A VPN extension with encryption protocols only protects your browser traffic and not any other data.

How to Choose the Best Firefox VPN?

Although Firefox VPN add-ons are mainly proxy extensions, they still need to adhere to the core principles of VPNs which are speed, privacy and security

With so many choices available online, it might get overwhelming to narrow down the one that’s most suitable for you. However, I’ve listed below a few important factors that you need to look into that may help you differentiate between your choices:

  1. Company reputations

One downside about CyberGhost worth mentioning is its ad-blocking feature. CyberGhost does not block advertisement pop-ups on HTTPS websites. However, the ad-blocking feature is workable on Windows, Mac, and iOS devices, which is more than sufficient for general users looking to stream content online.

Unfortunately, CyberGhost does not have a free trial and the monthly plan can be quite pricey. On the other hand, the VPN service provider does have a 45-day money-back guarantee and their longer-term plans are much most cost-friendly.

The free extension does not allow much configuration options and it offers a limited choice of four locations only, whereas their premium subscription plan lets you gain full access to their servers in over 70 different countries

In terms of performance, their upload and download speeds are proven to be slightly better than the other providers. So, you can expect an instantaneous connection to stream geo-locked media content without any need for buffering time.

On the other hand, Hotspot Shield is a brainchild of a US-based company called AnchorFree. Being part of the Five Eye Country means the company needs to abide by the country’s mandatory data retention rule and have to hand over any data upon request from the authority.

Hotspot is safe to use as they will not expose your original IP address, DNS, or WebRTC information while you’re connected to their service. However, the company’s logging policy is a little confusing. Hotspot Shield claims that they do not keep logs of your online activity, yet there are a few areas where they mention using customer data for a variety of purposes.

If you’re on the free version, you may expect to see some advertisements as the company teams up with a few third parties. Nonetheless, you need not worry about your privacy as the service provider will only hand out anonymized IP addresses and they will not sell user browsing history to the advertisers.

The paid version lets subscribers connect to five different devices at the same time with just a single account. This means users do not need to pay extra for securing their entire household with only one VPN service.

While Hotspot Shield’s subscription plans may not be the most affordable, they do come with 45-day refund policy for you to get your money back in case you do not fancy their services. You can also make a free Hotspot Shield account to test out their paid services with their 7 days free trial. But you do need to remember to cancel the trial before the time’s up, otherwise, they will automatically start charging you for their monthly service.

Zenmate Best Mozilla Firefox VPN

ZenMate is a straightforward VPN that is designed specifically to support non-technical users who want an easier way to protect their privacy online. The website itself has no confusing jargon or complicated feature lists that can rack up a major headache.

ZenMate operates under Germany’s jurisdiction, which happens to be part of the 14 Eyes Alliance that shares information with other countries as and when required. With this in mind, the company actually does keep some logs on users and their online activity.

The 128-bit and 256-bit military-grade encryption employed by the company ensures that all your user data and privacy are securely hidden from outsiders. Other than that, the VPN service provider even delivers OpenVPN, L2TP/IPsec, and IKEv2 services as part of their tunneling and encryption protocols.

Unfortunately, ZenMate currently only offers slightly over 30 servers across 30 different countries all around the world. This is a considerably smaller number compared to other major VPN providers. On the other hand, the majority of the servers available are torrent-friendly, which you can easily find through ZenMate’s user-friendly Mozilla Firefox browser extension.

The ZenMate seamlessly unblocks US Netflix media libraries from anywhere around the world to allow you unlimited access to TV shows and movies. Although the connection speed with ZenMate may be a tad bit slower than what other competitors offer, it’s unlikely you’ll notice any difference.

ZenMate’s free Firefox extension provides a simple way to enable and disable the VPN service from within the browser interface. There’s a simple console in the extension that allows you to pick and connect to a location with a few simple clicks.

The free extension offered is super bare-bones and offer only the very basic features you’d get from a VPN. But before you do decide on subscribing to their premium packages, you get to first test them out with ZenMate’s seven-day free trial. And even after you’ve paid, you get further protection with their 30-day money-back guarantee. There’s absolutely no harm in taking this out for a spin.

#7 IPVanish – The Best Mozilla VPN in Terms of Performance

IPVanish Best Mozilla Firefox VPN

IPVanish has a fast and reliable connection that works flawlessly. It has 1,300 servers in over 75 locations to allow this VPN to deliver an impressive global coverage. IPVanish’s performs up to five times faster for short hop connections while long-distance shows an average increase of 15% in download speeds.

Sadly, this popular VPN service is based in the US that is part of the 5-eyes country and is required to hand over your data to the US authorities. However, since the provider does not keep any usage logs plus, they offers impressive security features like OpenVPN, IKEv2 Kill Switch, Private Check, and Password Generator. In any case, there haven’t been any direct evidence to say that jurisdiction will affect user privacy, so you can still count on IPVanish to secure your information.

This VPN service provider goes one step further by offering you a level of control over their OpenVPN setup.

The Best VPNs for Firefox Review – Frequently Asked Questions (FAQ)

Is there free Firefox VPN?

Yes, but I strongly recommend against it. They’re more prone to leakage of personal information and user data. They may not function equally as good as paid VPN services due to slower connection speed and data allowance.

However, if you’re tight on a budget – I’d recommend getting CyberGhost VPN as it comes with 45 day money back guarantee which allows you to fully explore its features. So, if you’re unsatisfied with their VPN service just activate the day money back gurrantee.

What is a Firefox VPN add-on?

A VPN add on, also known as extension, is an extra, browser-based protection service that some VPN providers offer.

Add-ons are mostly simpler and lighter versions of a full VPN. However, since most of them are merely proxy extensions, they do not offer the same benefits that come with the main VPN desktop app. The main reason some people would prefer to install a VPN add-on is for a lighter way to access geo-blocked content with faster speeds compared to a full VPN.

Should I use a Firefox VPN Browser Extension or Full VPN?

While a Firefox browser extension is lightweight, it does not offer the same level of protection as a dull desktop VPN. For those whose concerns are only to access geo-blocked content, a VPN browser extension may suffice.

For those who are worried about their privacy and security, you’ll typically find that most VPN providers include Firefox add-on as part of their more comprehensive VPN package. Where possible, users should sign up for a full VPN that provides Firefox add-ons alongside mobile and desktop apps to ensure that you’re fully protected across all your devices.

What are the benefits of using VPN extensions on Firefox?

Adding a VPN extension to your Firefox browser opens up a wide array of benefits to keep your connection secure. While it is not the same as installing a VPN app, these proxies have niche uses as well. Below are a few scenarios where of installing a VPN extension comes in handy:

Special Case Uses

Proxies tend to be lighter on system resource usage due to their limited functionality. This is great especially for those who are using a less powerful laptop and do not want to drain your system resources.

Specialized Risk Control

Internet browsers are one of the most vulnerable targets to get hacked by external parties – all browsers are prone to security risks. If you don’t want a full-fledged VPN application that takes up the majority of your resources, you can settle for defending your information and hiding your identity through a VPN proxy extension specifically for your browser.

Ad Blocking

Some VPN extensions come with additional features like ad blocking, tracker avoidance, and cookie management. This helps to remove the junk out from the net before it reaches you, however, it may cause some web pages to look funny.

Preventing WebRTC Leaks

Mozilla Firefox and Chrome browsers have a security vulnerability whereby your IP address could easily be leaked. Some VPN extensions now even have a built-in WebRTC leak prevention to ensure this type of incident will never happen to you.

Are browser extensions the same as Firefox VPN applications?

Browser extensions only take care of online traffic on the browser while the application takes care of any and all online connections.

VPN browser extensions are proxy service extensions that redirect your online traffic to other servers. This method comes in handy when you need to access geo-restricted content or want to access a website from a different IP address.

VPN applications work in a similar manner. They redirect the user’s traffic to one of their server locations. However, one thing VPN applications do differently is that they encrypt and redirect user’s traffic to ensure no one is able to get their hands on the encrypted traffic.

Firefox extension is more vulnerable to cyber-attacks and other malicious activities on the internet. None of your sensitive information will be safe, and you will still be open to all sorts of cybercrimes when you’re using the proxy service.

VPN applications offer full-on protection services with their military grade-encryption. But this type of heavy usage does take a toll on your internet speed. You may experience a significant drop in connection speed while using the VPN application compared to the proxy extension.

Is using Firefox VPN legal?

Yes, using a Firefox VPN is completely legal. It is in your right to protect and encrypt all your internet connection to protect your personal data. It is the same concept as using an envelope to cover your letters. Some information is better kept private to ensure you’re not vulnerable to all kinds of malicious cyber-attacks.
