Windows 10 warns me to use a "Microsoft-verified" app

In certain versions of Windows 10, you may receive a notification with a warning about Microsoft-verified apps when you run the Waterfox installer.

Any copy of Waterfox downloaded from www.waterfox.net is safe to install, so choose “Install anyway”.

Note

• You can also download and install Waterfox from the Microsoft Store.
• Using Windows 10 in S mode? See Windows in S mode won’t let me install Waterfox.

If you do not see the option to “Install anyway”, follow the steps below to change your system settings.

1. Open the Windows 10 start menu and select Settings.
2. Click on Apps in the Windows Settings menu.
3. In the Apps & features section go to Choose where to get apps, click on the dropdown menu below and select one of the options that allows you to install from Anywhere.
4. Run the Waterfox Installer again. Your Windows may now allow it to install Waterfox.
