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 ;-)Edit: Actually now that I think about it I'm saving this to avoid using Edge myself in the future. Thank you!
is the same as
-Command “thing”
