A VPN is crucial for safeguarding your privacy by shielding your IP address from websites you visit and your internet service provider (or public WiFi host) from monitoring your browsing activity. Additionally, it enables you to watch your preferred shows, movies, and sports events even when you’re traveling outside of your home country.

When it comes to selecting a VPN service, trustworthiness is of utmost importance, as it takes the place of what your internet service provider is capable of monitoring. Proton VPN is a VPN service that you can have confidence in because:

  • We are headquartered in Switzerland, a country that has some of the most robust privacy laws globally.
  • Our no-logging system has undergone an independent audit.
  • Swiss regulations prohibit us from being required to initiate logging procedures.

To install a VPN browser extension on Firefox, you need to sign up for a Proton VPN Plus account and then add the extension to Firefox by clicking on “Add to Firefox” on Firefox Add-ons. For quicker access to the extension, click on the Extensions icon in the browser toolbar and select the gear icon next to the ProtonVPN extension, then click on “Pin to Toolbar.”


You can install the extension on multiple Firefox-based browsers, such as LibreWolf, Waterfox, or any other browser based on Firefox 109.0 or newer. Keep in mind that each browser using the extension counts as one of your ten VPN connections.

  1. Register and purchase a Proton VPN Plus subscription.
  2. Install the extension. Look for the Proton VPN extension on Firefox Add-ons and install it.
  3. Log in to your account and select Quick Connect to connect to a server.


That’s it! Now you can enjoy browsing the internet securely and privately.

You can either utilize the Quick Connect button to automatically connect to the quickest VPN server based on your location or manually search for a particular server or country.

To circumvent censorship restrictions, connect to a VPN server located in a region that doesn’t censor online content. For instance, if you’re in Iran or Russia, connecting to a server in the EU can grant you access to an uncensored internet.


If you want to watch content from popular streaming services while you’re traveling, connect to a Plus server in your home country to gain access.
