Get a Firefox VPN extension & protect your privacy

Connecting to a Firefox VPN proxy is the key to staying safe online. Surfshark encrypts your traffic and hides your IP address so neither we nor anyone else can see what you do online. 

Although we have plenty of servers, you won’t need to waste time searching for the best one — Surfshark’s Auto-connect feature automatically provides the fastest connection, regardless of your location.

Surfshark VPN offers unlimited simultaneous connections. With no need to worry about VPN data caps, you can stay protected not just when using Firefox but also on other devices or operating systems —  all at the same time.

Surfshark’s CleanWeb feature acts as an ad blocker, preventing ads, trackers, and malware from compromising your security. This keeps your surfing experience smooth at all times.

With Surfshark’s Bypasser (split tunneling) feature, you can choose which apps or services bypass the VPN connection. This can improve performance, making accessing services that don’t require complete VPN protection easier.

Surfshark offers more than 3,200 dedicated servers in 100 countries. If you ever experience a slowdown, finding a less crowded server is as simple as can be.

Setting up a VPN doesn’t have to feel like a chore. Surfshark’s complete security suite is extremely easy to install, boosting your online security in no time.

Surfshark’s Kill Switch instantly disconnects you from the internet if your VPN connection drops. This prevents accidental data exposure or leaks, keeping your Firefox browsing secure at all times.

Dynamic MultiHop, our double VPN feature, routes your data through two VPN servers at once. By using Surfshark with Firefox, you double encrypt your information for enhanced privacy.
