Top 5 Best VPN Extensions for Mozilla Firefox 2021

This curated overview of top 5 best VPN extensions for mozilla Firefox 2021 focuses on useful options, standout features, and details worth checking before making a choice.

This guide explains why these are the best VPN extensions for anyone using the Mozilla Firefox browser.

ExpressVPN

ExpressVPN tops the list for the best VPN extension for Firefox because it offers great security and lightning-fast connection speeds. ExpressVPN has over 3,000 servers in 94 countries.

While using the Firefox browser extension, users can connect to a server location of their own choosing and stream a series of their favorite videos in HD.

You can connect up to 5 devices simultaneously, including smartphones, Chromebooks, and iPads. You can easily download the ExpressVPN extension on Firefox and start surfing the web anonymously.

ExpressVPN offers 256-bit AES encryption, which is the best encryption by far. ExpressVPN also offers additional security features like Network Lock Kill Switch and DNS leak protection to conceal the real identity of the user.

NordVPN

NordVPN is another strong contender on this list, with over 5,500 servers in 59 countries. This Firefox browser extension can work as a stand-alone, i.e. without using a VPN client, and offers good speeds, and world-class security features.

NordVPN encrypts traffic using standard 256-bit encryption and blocks malware and other threats using the CyberSec feature.

To stream, you'll be glad to know that NordVPN works with popular streaming platforms like Netflix, Amazon Prime Video, HBO, and Hulu.

This VPN extension is also ideal for privacy-conscious users. NordVPN has a strict no-logs policy and smart kill switch to ensure that your IP is never revealed. In addition, NordVPN blocks WebRTC leaks and offers a useful Adblocker ad blocker that protects you from malware, phishing, and other threats.

You can connect up to 6 devices at once with a single NordVPN license. If you switch between Firefox and Chrome, you'll be pleased because NordVPN also offers an extension for Chrome.

You can get full access to all NordVPN features risk-free using the 30-day money-back guarantee. You can always request a refund during the trial period if you feel it's not the right choice for you.

HotSpot Shield

HotSpot Shield is a premium VPN that offers both free and paid extensions for the Mozilla Firefox browser.

This extension is very easy to use as it does not require registration. All you need to do is install the extension in Firefox and connect to the service with one click.

The free version is location-restricted and only allows you to connect to US servers. This can lead to slow connections during peak hours due to overcrowded servers. If you want access to all 1,800+ servers along with cloud-based malware protection and more, you'll need to upgrade to the premium version of HotSpot Shield.

The variety of security features offered in both the paid and free HotSpot Shield extension is truly impressive. It provides cookies and adblocker (ad blocker) as well as WebRTC protection to prevent unwanted IP leaks. You can find these features in the configuration menu and customize them according to your personal security preferences.

Unfortunately, the ad blocker in the free version does not work as expected, as users continue to receive annoying ads on YouTube. For more reliable performance, it is recommended to use the premium HotSpot Shield extension.

Private Internet Access

Private Internet Access, or PIA, offers an extensive network of more than 29,000 servers in more than 75 locations. As PIA's name suggests, security and privacy are at the heart of this VPN's operations.

PIA offers good speeds on all of its servers. You can stream movies on Netflix and BBC iPlayer with no lag. APV can easily detect PIA and notify when you try to access geo-blocked content.

PIA provides a kill switch that automatically disconnects from the Internet in case you lose your VPN connection. It also offers DNS leak protection, so you don't have to worry about your identity being exposed while browsing the web.

PIA has a proven no-logs policy, which means your personal data will not be shared with anyone. The provider also offers a 30-day money-back guarantee, so you can use the service with complete peace of mind that you're risk-free.

TunnelBear

TunnelBear provides a user-friendly Firefox browser extension. You can download it from the add-on store for Firefox, create an account, and connect to a server in a location of your choice.

While TunnelBear doesn't have as many security features as the competitors on this list, it's enough to protect your data and keep your location anonymous. This VPN uses Vigilant Mode, which is basically a kill switch, to block unsafe traffic in case the VPN connection fails.

Similar to the other services on the list, TunnelBear also offers IP and DNS leak protection. The author of the article ran some tests and was not able to detect any DNS or IP address leaks.

TunnelBear offers a VPN extension for Firefox for free, but it has a 500MB data limit per month. The free extension can be a great choice for casual browsing and data protection, but for unlimited secure browsing and streaming we recommend the premium TunnelBear VPN extension.
