Clear browser history
<p>I wrote the following code to clear the browser history and it's working correctly in Internet Explorer but it does not work in Mozilla Firefox. How can I solve this problem?</p>

<pre><code>&lt;script language="JavaScript"&gt;
function DisablingBackFunctionality()
{
    var URL;
    var i ;
    var QryStrValue;
    URL=window.location.href ;
    i=URL.indexOf("?");
    QryStrValue=URL.substring(i+1);
    if (QryStrValue!='X')
    {
        window.location.href="http://localhost:8085/FruitShop/";
    }
}
&lt;/script&gt;
</code></pre>

<p>I'm writing this code in <code>&lt;header&gt;</code> section. </p>
