Wtf I just install Firefox and literally don't even register that Edge exists. Have used 11 since the beta. People make this into some very big issue while ignoring that the only real monopoly in this space is Google.
How do you install Firefox without using Edge? By default there is no other browser on Windows, and presumably you need a browser to visit firefox.com, no? Or you carry Firefox installer around on a USB with you?
powershell -Command "& {Invoke-WebRequest -Uri 'https://download.mozilla.org/?product=firefox-latest&os=win64&lang=en-US' -OutFile 'Firefox.exe'}"
Not saying it's ergonomic but since you asked ;-)
