Connecting, switching servers, and basic extension controls

Sign in and authenticate: You’ll need your Mullvad account number or login credentials tied to your account. This is how the extension verifies you and loads your preferred settings.
Choose a server: The extension lists Mullvad’s server locations. Pick one near you for better latency, or select a strategic location for access to region-restricted content.
Start/stop the tunnel: A prominent connect/disconnect button lets you quickly enable or disable the tunnel for the current browser session.
Kill switch and DNS: The extension typically offers options to enable a browser-level kill switch and DNS leak protection. Enabling these helps prevent traffic leaks if the VPN disconnects unexpectedly.
Auto-connect: You can set the extension to connect automatically when the browser launches or when you connect to a new network.
Proxy mode Socks/HTTP proxies: Some Mullvad setups let you use a browser proxy mode via the extension, useful for specific privacy workflows or compatibility with certain apps.

Key security features you’ll want to enable

Kill switch: Prevents traffic from leaving your browser if the VPN tunnel drops, protecting sensitive data from exposure
DNS leak protection: Ensures DNS queries are resolved through Mullvad’s DNS servers, not your ISP’s
WebRTC leak protection: Helps prevent IP leakage through WebRTC technology inside the browser
IPv6 leak protection: When possible, blocks IPv6 traffic that could bypass the VPN
Proxy support: If you’re in a scenario where you want to route browser traffic through a SOCKS5 proxy as provided by Mullvad or your configuration, the extension can help manage that setup

Mullvad extension vs Mullvad desktop app

Scope: The extension focuses on browser-level control and, in some configurations, proxy options. The desktop app covers the entire device, including system-wide routing, network-level protections, and GUI-based server selection.
Convenience: The extension is handy for quick privacy toggling while browsing, but for full privacy hardening, many users pair it with the desktop app.
Features: The desktop app typically offers deeper configuration options, including global kill switch across all apps, DNS settings at the system level, and more extensive server management. The extension complements this by handling in-browser privacy controls and, in some cases, proxy-based setups.

Privacy and logging: what Mullvad stands for Client configuration (example, exportable as .ovpn)

No-logs philosophy: Mullvad is known for a privacy-centric stance, including a policy that emphasizes minimal data collection and strong anonymity—account numbers rather than emails, and support for anonymous payments
WireGuard-based: The extension leverages Mullvad’s WireGuard-backed tunnels for fast, secure connections with robust cryptography
Audits and transparency: Mullvad has published information about its privacy practices and server operations, with independent audits on certain aspects of privacy and security. Always check the latest transparency reports for updates

Use cases: when to use Mullvad extension

Heavy browser users who want quick privacy toggling and protection without opening a full VPN app
Users who want to route browser traffic through a secure tunnel while leaving other apps on their device unaffected depending on your OS and configuration
Scenarios requiring safe browsing on public Wi-Fi networks, where quick browser-level protection reduces risk
When privacy-conscious users need to avoid DNS leaks and exposure from WebRTC in the browser

Streaming, torrenting, and performance considerations

Streaming: Mullvad’s servers are generally reliable for streaming, but latency and speed depend on your location, server choice, and network conditions. If you experience buffering, try a nearby server or a server optimized for streaming if available
Torrenting: Mullvad supports P2P in many locations. however, always verify local laws and Mullvad’s current terms. The extension can help protect browser traffic, but for full P2P privacy, use the desktop app’s network-level protections
Speed: WireGuard typically offers strong performance, but VPN speed varies by server load, distance, and your baseline connection. The extension’s impact on speed is usually minor compared with the full app, but you may notice some difference when using browser-level routing versus system-wide routing

Troubleshooting common issues

Don’t see a server or can’t connect: Refresh, try a different server, ensure you’re signed in, and confirm that the Mullvad service is operational in your region
DNS leaks: Re-check DNS settings in the extension, and consider enabling DNS leak protection or using Mullvad’s DNS servers
WebRTC leaks: If WebRTC remains a concern, enable WebRTC protections in the extension and in your browser settings
Extension not loading or crashing: Disable conflicting extensions, update your browser, or reinstall the Mullvad extension
Mobile compatibility: For iOS/Android, use the Mullvad mobile app, and consider using the browser extension on mobile browsers where supported note that some features are limited on mobile platforms
