Frequently asked questions

Is it possible to connect to a VPN for free using Mozilla Firefox?

Technically, the answer is yes, but it is not advisable. You might only be able to surf for a few hours using free VPNs due to their bandwidth restrictions. Streaming platforms may not be accessible since IP addresses are frequently prohibited and not renewed, making it difficult to unblock them.

But more importantly, they could sell your data to provide a free VPN.

You may also not receive enough IP and WebRTC leak security, which means that your ISP and authorities can see your sensitive data.

What Is a VPN Add-on?

VPN add-ons or plugins are lighter versions of VPNs offered by some VPN companies. They provide a faster, streamlined way to access geo-restricted content, but don’t offer the full spectrum of benefits a standalone VPN does.

Is there a difference between using a VPN add-on and a VPN application?

While VPN add-ons are small and easy to use, they lack certain features like a kill switch and split tunneling found in standalone VPN applications. Therefore, most VPN providers recommend using the add-on as a part of a larger VPN package for optimal security and privacy.

Should I use a firefox VPN browser extension or a full VPN?

A Firefox add-on or extension does not provide the same protection level as a desktop VPN or mobile app.

This implies Firefox extensions aren’t ideal for privacy- or security-conscious users. Others who merely need geo-restricted content may only need a VPN browser add-on.

Due to security and privacy concerns, most VPN providers provide the Firefox add-on as part of a larger VPN package and urge customers to utilize both.

I propose signing up for a comprehensive VPN offering Firefox add-ons and mobile and desktop applications. So, all your gadgets are safeguarded.

Why should I use a VPN?

Using a VPN enhances your online privacy and security. It is especially important if you’re dealing with sensitive data over the Internet or using public WiFi. A VPN encrypts your internet traffic, making it secure and private.
