Create a shell and attempt to run a URL.
This works for me (save as whatever.hta and execute it) on my system. Clicking on the button opens Google in Firefox:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>
<title>HTA Test</title>
<hta:application applicationname="HTA Test" scroll="yes" singleinstance="yes">
<script type="text/javascript">
function openURL()
{
var shell = new ActiveXObject("WScript.Shell");
shell.run("http://www.google.com");
}
</script>
</head>
<body>
<input type="button" onclick="openURL()" value="Open Google">
</body>
</html>
