Actualización por script de firefox

Cansado de descargar soft para los paquetes de firefox para el sccm me interese en buscar un método de detección por script e instalacion y el codigo ya no recuerdo de donde lo saque (gracias a la web si la recuerdo la nombro), pero si que lo adapte a mis necesidades haciendo un hibrido

básicamente miramos en la web la version, la comparamos con la instalada, descargamos la version que queremos he instalamos (en mi caso la version en catalán por petición del cliente)

function Get-OnlineVerFirefox
{

    [cmdletbinding()]
    param (
        [Parameter(Mandatory=$false, 
                   Position=0)]
        [switch]
        $Quiet
    )

    begin
    {
        # Initial Variables
        $SoftwareName = "Mozilla Firefox"
        $uri = 'https://product-details.mozilla.org/1.0/firefox_versions.json'


        $hashtable = [ordered]@{
            'Software_Name'    = $softwareName
            'Software_URL'     = $uri
            'Online_Version'   = 'UNKNOWN' 
            'Online_Date'      = 'UNKNOWN'
            'Download_URL_x64' = 'UNKNOWN'
            'Download_URL_x86' = 'UNKNOWN'

        }

        $swObject = New-Object -TypeName PSObject -Property $hashtable
    }


   Process
    {
        # Get the Version & Release Date
        try

            $message = $("Line {0} : {1}" -f $_.InvocationInfo.ScriptLineNumber, $_.exception.message)
            $swObject | Add-Member -MemberType NoteProperty -Name 'ERROR' -Value $message
        }
        finally
        {


        # Get the Download URLs
        if ($swObject.Online_Version -ne 'UNKNOWN')
        {

            $swobject.Download_URL_X64 = $FirefoxDownloadX64

    }
    End
    {
