How to set up and use Proton VPN’s Firefox extension
Create an account
To start using Proton VPN on Firefox, sign up for free or buy a paid Proton VPN Plus account.
With our paid plans, you can use Proton VPN on up to 10 devices at the same time, connect to over 12,000 high-speed servers in over 110 countries, and access premium features.
Download the extension and log in
- Search for and add the Proton VPN extension from the Firefox Add-ons.
- Once the app is installed on Firefox, run it and log in with your Proton VPN username and password. Proton Unlimited, Proton Familly and Proton Visionary users already have a Proton VPN account and can sign in with existing Proton credentials.
Connect to a server
You can automatically connect to the fastest VPN server for your location or choose to connect to any specific server that is available on your plan.
The data traveling between your device and the VPN server is encrypted, meaning:
- Your internet service provider cannot monitor your activity.
- Websites see the IP address of the VPN server you're using.
You can check your IP address whenever you're connected to find your VPN server's address.
