How to Install Waterfox on Windows - Waterfox

Download the installer from the official Waterfox website, run the setup file, and follow the on-screen prompts to complete your Waterfox installation on Windows. This Firefox-based browser offers XUL extension support and performance optimizations tailored for Windows users.

Download Waterfox

Visit the Waterfox download page and select the Windows installer version. The file downloads quickly—typically under a minute on standard connections. Save it to your Downloads folder or any accessible location. You'll see a .exe file once the download finishes.

No registration required. No email signup needed.

Running the Windows Installation

Double-click the installer file to launch the setup wizard. A window appears asking for permission—click "Yes" to proceed. The installer automatically detects your Windows version and system specifications. Choose your preferred installation directory (default is usually fine) or customize the folder path.

Select whether you want a desktop shortcut created during Waterfox setup. Most users leave this checked for quick access.

Complete the Setup Process

Click "Install" and wait for files to copy to your system. Installation typically takes 30–60 seconds. Once finished, you'll see a completion screen. Check the box to launch Waterfox immediately, or close the installer and open it manually later.

The browser window opens with the home page ready.

Post-Installation Configuration

Your first launch prompts you to set Waterfox as your default browser—optional but recommended. Import bookmarks from Chrome, Firefox, or Edge if needed. The XUL extension support makes this browser unique; you can install legacy extensions unavailable in standard Firefox. Check Settings > Extensions to begin customizing.

Recommendation: If you need a lightweight, extension-rich browser experience on Windows, Waterfox 6.6.9 delivers both. The installation process takes minutes, and you're immediately ready to browse. Keep your Windows system updated for optimal performance.
