its four words

Yeah, totally.

Just imagine trying to do this with Windows Powershell, without a package manager like chocolatey to make it simple like linux…

$workdir = "c:\installer\"

If (Test-Path -Path $workdir -PathType Container)

{ Write-Host "$workdir already exists" -ForegroundColor Red}

ELSE

{ New-Item -Path $workdir  -ItemType directory }

$source = "https://download.mozilla.org/?product=firefox-latest&os=win64&lang=en-US"

$destination = "$workdir\firefox.exe"

if (Get-Command 'Invoke-Webrequest')

{

     Invoke-WebRequest $source -OutFile $destination

}

else

{

    $WebClient = New-Object System.Net.WebClient

    $webclient.DownloadFile($source, $destination)

}

Start-Process -FilePath "$workdir\firefox.exe" -ArgumentList "/S"

Start-Sleep -s 35

rm -Force $workdir/firefox*
