Setting up a VPN for Firefox helps you unlock geo-restricted content on platforms like Netflix, YouTube, and Steam. A VPN also protects your browsing history, phone number, and IP address from being tracked or leaked by hackers.
However, not all VPNs are secure, reliable, or affordable. Below, we detail all the best Firefox VPNs.
1. LightningX VPN – The Most Affordable Firefox VPN

2. Mozilla VPN – Firefox Dedicated VPN
Mozilla VPN is an open-source paid VPN developed by Mozilla, offering high compatibility with Firefox. Below are its key features.
- Speed Performance: Mozilla VPN utilizes the open-source, lightweight WireGuard protocol, a key factor for good connection speeds. However, its limited number of nodes may result in suboptimal speed performance.
