    Proton VPN Browser Extension

    Proton VPN Browser Extension

    Proton VPN Browser Extension

    The Proton VPN Browser Extension repository houses the code for an official browser extension that lets users quickly secure their web browsing traffic through ProtonVPN from within browsers like Firefox and Chrome without routing all system traffic. This extension provides users with a convenient way to encrypt and anonymize HTTP requests, hide IP addresses, and prevent tracking while browsing, acting independently of the full OS-level VPN clients. Because browser extensions are constrained by browser APIs, this extension focuses on securing in-browser connections, protecting privacy specifically within the browser context rather than across the entire operating system.
