I have tried using the code below but it only display results in Chrome and Mozilla not working in IE6. 

<div id="example"></div>

<script type="text/javascript">

txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";

document.getElementById("example").innerHTML=txt;

</script>

Output:

Browser CodeName: Mozilla

Browser Name: Netscape

Browser Version: 5.0 (Windows)

Cookies Enabled: true

Platform: Win32

User-agent header: Mozilla/5.0 (Windows NT 5.1; rv:12.0) Gecko/20100101 Firefox/12.0

I need to get the version "Firefox/12.0" only.

PPK's script is THE authority for this kind of things, as @Jalpesh said, this might point you in the right way

var wn = window.navigator,
        platform = wn.platform.toString().toLowerCase(),
        userAgent = wn.userAgent.toLowerCase(),
        storedName;

// ie
    if (userAgent.indexOf('msie',0) !== -1) {
        browserName = 'ie';
        os = 'win';
        storedName = userAgent.match(/msie[ ]\d{1}/).toString();
        version = storedName.replace(/msie[ ]/,'');

        browserOsVersion = browserName + version;
    }
