Whether you're using Windows 10 or the latest Windows 11, this guide will help you set Firefox as your default browser with minimal fuss. Setting Firefox as your default browser on Windows has become a bit more involved due to changes in how Windows manages default applications. With the release of Firefox version 126, we introduced a new guidance notification feature to help you easily navigate these changes.

How to set Firefox as your default browser

Make Firefox your default browser in Firefox Settings

1. In the upper-right corner of your screen, click to open the Firefox menu.
2. Select Settings.
3. In the General panel, find the Startup section.
4. If Firefox isn't currently set as your default browser, you'll see the message Firefox is not your default browser. Click the button.
5. If you see this toast notification, it indicates that the one-click default setting did not work, and you will need to take additional steps in your Windows settings.

   

To easily open Firefox later, add a shortcut to your taskbar:

1. On your computer, open Firefox.
2. At the bottom, in the Windows taskbar, right-click Firefox.
3. Click Pin to taskbar.
