Answer 1

navigator.plugins will have an array of plugins that you can check.

This exists for Firefox, Chrome, and IE (at least version 8, I don't have a lower version to test)

Here's what the array looks like in webkit:

solved:

document.writeln("<TABLE BORDER=1><TR VALIGN=TOP>",
   "<TH ALIGN=left>i",
   "<TH ALIGN=left>name",

for (i=0; i < navigator.plugins.length; i++) {
   document.writeln("<TR VALIGN=TOP><TD>",i,
      "<TD>",navigator.plugins[i].name,
      "<TD>",navigator.plugins[i].filename,
      "<TD>",navigator.plugins[i].description,

You can get browser plugins by this javascript code:

<script type="text/javascript">
var x=navigator.plugins.length; // store the total no of plugin stored 
var txt="Total plugin installed: "+x+"<br/>";
txt+="Available plugins are->"+"<br/>";
for(var i=0;i<x;i++)
{
  txt+=navigator.plugins[i].name + "<br/>"; 
}
document.getElementById("example").innerHTML=txt;
</script>
<br/>
<script>
