To emulate Windows Phones, use Microsoft Edge's built-in emulation.

# Firefox' Responsive Design Viewįirefox has a responsive design view that encourages you to stop thinking in terms of specific devices and instead explore how your design changes at common screen sizes or your own size by dragging the edges. Test your site on browsers running on real devices to be certain everything behaves as expected. Even though Device Mode can simulate a range of other devices like iPhones, we encourage you to check out other browsers solutions for emulation. Your job doesn't end with ensuring your site runs great across Chrome and Android.
