What To Consider Before Selecting a Free VPN Extension for Firefox

There are some essential things you should consider which free VPN extension for your Firefox browser you would use. Let’s look at them below. 

1. Security

A VPN extension’s security features are crucial in ensuring that every connection that passes through your Firefox browser is secure. Some free VPN extensions on Firefox are merely proxies that do not provide military-grade encryption. These types of Firefox extensions will only give you the ability to bypass geographical restrictions. On the other hand, those that encrypt your connection are the best if your concern is security. 

2. Privacy

Privacy features will determine your level of anonymity on the internet. Free VPN extensions on Firefox with many privacy features are more likely to make it challenging for anyone to track you online. In contrast, those with little or no privacy features will put you at the risk of discovery. 

3. Server Network

The more servers available for use on a free VPN’s Firefox extension, the more options users have to access geo-blocked content or online censorship. So, you should find a free VPN with a Firefox extension that gives you access to a great server network. 

Frequently Asked Questions About the Best Free VPN Extension for Firefox

Can I use a free VPN extension on Firefox?

Yes, you can use a free VPN extension on Firefox. Above, we have recommended the best free VPN extensions you can use on Firefox.

Limits on the server network, bandwidth, speed, security, and privacy features might limit what you can achieve with free VPN extensions. It is why we have also recommended risk-free VPN extensions you can use on Firefox. 

Can I use free VPN extensions on Firefox’s mobile browser?

No. Unfortunately, while there are a few Firefox mobile extensions you can use on Android, many VPNs don’t support mobile extensions. Additionally, there is no support for add-ons or extensions on iOS devices. You can always download the VPN application on your device and use split-tunneling to protect only your browser. 

Are there free VPN extensions on Firefox that will not work without the VPN app installed on your device?

Yes, there are free VPN extensions that require you to install their VPN application before using them. In such cases, you will need to have both the extension and the application before you can use the extension. For example, ExpressVPN, a risk-free VPN, will not work without you installing its VPN application. 

Should I use a free VPN application or a free VPN extension for Firefox?

There is no straightforward answer to this question as it depends entirely on what you want to do with a VPN. VPN applications usually have more features than VPN extensions. Think of a VPN extension as a lightweight version of a VPN application for browsers. In addition, some VPN extensions are just proxies and don’t encrypt your connection. So, if a free VPN extension is adequate for you, go for it. Otherwise, use an application.
