If you’re looking for a virtual private network (VPN) extension for your Mozilla Firefox browser, it can be difficult to choose the one that best suits your needs considering how many there are. If you’re having a difficult time deciding which to add to your browser, hopefully, this list will help. 
When choosing a VPN, you need to be very careful. VPNs with dubious intentions could see your entire browsing data, collect highly personal information and then sell it to other questionable parties. It should be noted that, if possible, you should always opt for the paid option. Premium VPNs not only offer additional features and locations but also take care of your privacy much better than any free VPN would. According to Andrew Defrancesco in order to generate revenue, free VPN share your information with advertisers, defeating the whole purpose of a VPN. Nonetheless, it’s understandable that not everyone can pay for such services, hence why this list will include free VPNs as well.
The best VPNs for your Mozilla Firefox browser
- NordVPN
Developed by Nord Security, NordVPN is one of the most popular VPNs out there, with more than 5,500 servers in 60 countries. NordVPN is available as a desktop client but also works as a browser extension and it’s not necessary to install the desktop version. However, VPNs as browser extensions only encrypt browser traffic.
As a browser extension, NordVPN works exceptionally well. It has a zero log policy so it’s certain that your data will not be shared or sold to anyone. Making a connection is super easy with just a click of a button, and it offers a “CyberSec” feature that will work as an adblocker, as well as protect you from malware, phishing attacks, and other threats. It does not have any other noteworthy features but that is to be expected as it’s a VPN add-on.
If you’re looking for a VPN to access geo-blocked content and streaming services, NordVPN can help with that. At the time of writing, it works on the majority of streaming platforms like Netflix, Amazon Prime, HBO, and Hulu.
NordVPN is a paid program/extension but it does have a 30-day money-back guarantee that works as a free trial. You can choose from three subscription plans. A 1-month plan is $11.95/month, billed every month. Purchasing a 1 or 2-year subscription plan is much cheaper. The 1-year plan is $4.92/month, with you being billed $59.00 the first year, and then $143.40/year. A 2-year subscription plan is $79.00/the first two years ($3.29/month), then $286.80/two years. While it may seem expensive, NordVPN always offers some kind of discount. You can use one subscription on up to six devices.
- ExpressVPN
Developed by Express VPN International Ltd., ExpressVPN is a leading virtual private network extension for the Mozilla Firefox browser. It has more than 3000 servers in 94 countries. It should be mentioned that for the extension to work, it’s necessary to install the desktop app as well.
ExpressVPN is one of the leading VPNs for a reason. Its strict zero logs policy ensures that your information is not shared with anyone and you can browse with no trace. ExpressVPN for Mozilla Firefox is easy to use and you can easily connect to a server of your choice. To make it more convenient, you can set up an automatic connection upon browser launch.
This Firefox extension works great to unlock geo-blocked content and is not detected by streaming services like Netflix, Amazon Prime, and HBO, allowing you to enjoy their content if they’re not available in your country.
ExpressVPN is a paid VPN so purchasing a subscription is necessary to use it. There is a 30-day money-back guarantee that works as a free trial. You can choose from three subscription plans, depending on what subscription length you want. If you want to pay on a monthly basis, the price is $12.95/month. A 6 months subscription plan is $9.99/month, with you being billed $59.99 every 6 months. A 1-year subscription plan is $99.95/year ($8.32/month). ExpressVPN is one of the more expensive VPNs but you can find plenty of discounts to make it more affordable. You can use one subscription on up to five devices.
- Windscribe
Developed by a Toronto-based company, Windscribe is a great addition to the list of best VPNs for the Mozilla Firefox browser. It has servers in 63 countries and 110 cities.
The Windscribe extension for Firefox not only works as a VPN but also blocks ads and trackers following you across the web, deletes cookies when you close the tab, and randomly rotates your user agent to reduce the chance of basic fingerprinting. It’s easy to set up and use, and is fast both in performance and internet speed.
Windscribe has both a free and a premium version. The free version gives 10GB of data per month and access to servers in over 10 countries. If you only need a VPN for limited use, this may be a great option for you. For those who need unlimited data and access to more servers, Windscribe offers 3 subscription plans. The monthly plan is $9/month. A 1-year plan is $49/per year ($4.08/month). You can also customize a plan, with $1 per location. If you want to use a VPN for things like streaming, the custom plan may be a great option, though keep in mind that some streaming services may detect it. Windscribe is one of the cheaper options, especially if you do not need many locations.
- Private Internet Access
With 35,000 servers in 77 countries, Private Internet Access has perhaps the largest VPN network. It does not collect any information about users, thus does not share it with anyone, ensuring your complete privacy when browsing. It’s a highly customizable Firefox extension that allows you to set it up in a way that connects to specific servers when you access certain websites.
Its zero-log policy ensures that you are not tracked and your data is not shared with anyone, ensuring privacy when browsing. It’s pretty easy to set up/use, has a fast connection, and has satisfactory speeds.
Private Internet Access is a paid program and offers 3 plans, differing only in subscription length and price. If you want to pay on a monthly basis, the subscription costs $9.95/month. A 1-year subscription is $39.95/the first year ($3.33/month), then $119.40/year. Overall, the cheapest plan is the 3-year subscription but you have to pay $79 in advance for the three years, and the price goes up to $358.20/three years after those initial three years. One subscription allows up to 10 connections.
While Private Internet Access has the largest VPN network in the world, it’s rather hit or miss when it comes to unblocking streaming services and their content. It may work on some streaming services like Netflix or BBC iPlayer but be detected by others like Amazon Prime Video.
- Hotspot Shield
Developed by AnchorFree, Hotspot Shield is primarily a VPN but also offers other features like protection against malware. The Hotspot Shield Mozilla Firefox extension is very easy to use, and does not require registration if you’re satisfied with 500Mb/day of data and only one location.
The VPN does not collect any personal information, and while it does collect IP addresses, they are deleted at the end of the VPN session. If you’re looking to unblock streaming services and/or their content, the premium Hotspot Shield version should work with services like Netflix, Amazon Prime Video, Hulu, and BBC iPlayer.
The Hotspot Shield VPN has one free and two paid subscription plans. The free Hotspot Shield version allows one connection, connection speeds up to 2 Mbps, and a daily limit of 500MB of data. The Hotspot Premium subscription plan costs $12.99/month or $95.88/year ($7.99) if you can pay in advance, and includes a VPN, up to five connections for one account, 115+ locations, unlimited data, and connection speed up to 1 Gbps. Also included are an anti-virus program, a spam caller blocker, and a password manager. The Premium Family plan costs $19.99/month or $143.88/year ($11.99) if you can pay in advance, and includes up to 25 connections for five accounts, 115+ locations, unlimited data, and connection speed up to 1 Gbps. Only the premium plans allow streaming and gaming modes. Both plans also come with a 45-day money-back guarantee. If you’re looking only for a VPN and plan to use it only for yourself, Hotspot Shield is not a great choice as it is quite expensive. However, it’s a good choice for families and/or bigger groups.
