Best Mozilla Firefox VPN Add-On That Actually Work In 2024

I love how easy Firefox add-ons make it to use a VPN when I’m browsing, but I get nervous when they offer only basic features and little to no security. Not all VPNs are made the same and some providers invest more in their add-ons than others.

I tested 30+ VPNs offering Firefox extensions to find out which ones really work. Based on my tests, I shortlisted a few that work well and offer great security and privacy features.

I’d recommend ExpressVPN since it’s the fastest and the most reliable provider. It also has a wide range of servers worldwide.

ExpressVPN Offer April 2024: For a limited time only, you can get an ExpressVPN subscription for up to 49% off! Don't miss out!

ExpressVPN has ultra-fast servers, making it easy to stream in high-def. My average download speed on its UK, US, and Australian servers was 60 Mbps. Considering that you only need 5 Mbps for HD quality, you’ll get hours of bufferless, lag-free streaming.

It’s easy to unblock international streaming platforms with ExpressVPN. I tested servers in the US and UK and they gave me access to Netflix within moments. It was just as easy to access other streaming platforms like Hulu, BBC iPlayer and HBO Max, etc. So, you’ll be able to watch your chosen libraries without a problem.

I was pleased to find the Firefox add-on is more than just a proxy; it gives you a direct link to the VPN. This sets it apart from many other providers because it protects your whole computer as you use it. Its security and protection protocols are off the charts, offering high power encryption, DNS leak protection, and a kill-switch as standard.

While ExpressVPN is expensive, it offers amazing deals — right now, you can save up with its 49% discount.

Based on my tests, ExpressVPN is the best all-rounder. It has ultra-fast speeds that allow you to stream without lag and it bypasses geoblocks with ease. It connects you directly to the VPN rather than acting as a proxy, so you can be sure your computer is protected.
