Mozilla has quietly made it easier to make Firefox the default browser in Windows 10. Microsoft currently provides an easier one-click method to make its Edge browser the default browser on Windows 10, but it’s not made this one-click method officially available for other web browsers.
Most likely fed up with this, Mozilla in version 91 of Firefox has reverse-engineered the process Microsoft uses to make Edge the default browser, simplifying the process to make Firefox the default browser on Windows 10 instead.
