<p>I can open the url with the 3 browsers using this Powershell script:</p>

<pre><code>Param(
[string] $url
)


[System.Diagnostics.Process]::Start("chrome.exe", $url)      
[System.Diagnostics.Process]::Start("firefox.exe",$url )


$IE=new-object -com internetexplorer.application
$IE.navigate2($url)
$IE.visible=$true
</code></pre>
