What if you’re using IE and Firefox. Well, you need to write one statement that will execute in IE, then another statement to run in the Firefox. This is also called a browser sniffer.
Here’s how you can do it.
First we’ll show you how to write a catch so it’ll run 1 statement if it is IE, and another if it’s any other browser.

<script type="text/javascript">
var browser = navigator.appName; //find the browser name

alert(browser); //popup with the browser name

if(browser == "Microsoft Internet Explorer"){
    alert("You are using IE");
}else{
    alert("you are using a different browser than IE");
}
</script>

Usually the code above suffices, because most JavaScript will either work in IE or the other browsers.
