Take Screenshot with Firefox - powershell

Question

I'm having a heck of a time figuring out why this simple command is not working.
I'm attempting to take screenshots of a list of domains using PowerShell and Firefox per [this article][1].
Currently I have the following code, but it does not produce screenshots and I'm unsure what is wrong code wise. Any assistance and/or a point in the correct direction is greatly appreciated.
$screenshotdir = "$PSScriptRoot\FF_Screenshots"
If(!(Test-Path -Path $screenshotdir)) {New-Item -Path $PSScriptRoot -Name "FF_Screenshots" -ItemType Directory}
function getFireFoxScreenShot() {
$importedCSV = Import-Csv .\Domains.csv
foreach ($url in $importedCSV) {
$domainName = $url.Name #example google.com
$domain = $url.Domain #example google (no tld)
if (-not ([string]::IsNullOrEmpty($domainName))){
Echo "Getting Screen Shot for: $domainName"
Start-Process -FilePath "C:\Program Files\Mozilla Firefox\firefox.exe " -ArgumentList " --screenshot $screenshotdir\$domain.png ", "$domainName" -Wait
}
}
}
getFireFoxScreenShot

Make sure to specify protocol (https:// or http://) as it is in the article you linked to:
# Tested with Developer Edition of Firefox
$domain = "example"
$domainName = example.com"
$screenshotdir = "C:\SO\56572800"
# This works
Start-Process -FilePath "C:\Program Files\Firefox Developer Edition\firefox.exe" -ArgumentList "--screenshot $screenshotdir\$domain-with-https.png", "https://$domainName" -Wait
# But doesn't work
Start-Process -FilePath "C:\Program Files\Firefox Developer Edition\firefox.exe " -ArgumentList " --screenshot $screenshotdir\$domain-no-https.png ", "$domainName" -Wait
From what I checked, if you don't specify https:// prefix (or http:// if applicable), it'll hang for a long time so you might have an impression that it's working.
As #lloyd mentioned in comments, you have to make sure that value of $screenshotdir is properly assigned and available to the function.
Also, it's a good practice to trim leading/trailing spaces from your command, even though in your example it still works with the spaces. I mean these ones:
HERE | HERE | HERE |
Start-Process -FilePath "C:\Program Files\Mozilla Firefox\firefox.exe " -ArgumentList " --screenshot $screenshotdir\$domain.png ", "$domainName" -Wait
