<html>
<head>

<title>Welcome to javaScript DOM...!</title>
</head>
<body id="body">
<a href="#" id="create" onclick="Create_Element()">Click To Create Element ...! </a>

<script>
function Create_Element(){
var body = document.getElementById("body");
var new_element = document.createElement("b");
new_element.innerHTML="Welcome To The New Element ... :)";
body.appendChild(new_element);
}
</script>
</body>
</html>

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
