Browser Detect Firefox Run Specific Code

[stevezz87]

I was wondering if anyone could give me a code that would detect if the visitor is using firefox and that if firefox is detected I could run a specific code. It would be really helpful. I'm doing this because in IE I have a code working perfect that does not work on Firefox but with an added code will work on Firefox however if I keep the added code in and visit from IE I have an error.

So basically I just need a code that detects the browser and has an if statement saying if the browser is firefox run this code.

Any help is appreciated
Thanks in advance.

<script type="text/javascript">
<!--

var isFF = (navigator.userAgent.split("/")[0].match(/mozilla/i))? true : false;

if(isFF){
    alert("Using Mozilla Firefox");
} else {
    alert("For other browsers");
}

//-->
</script>

That doesn't seem to work. It says using mozilla firefox when i open it with IE.

Try this:

<script type="text/javascript">
<!--

var IE = (navigator.appName.match(/internet explorer/i)) ? true : false;

if(IE){
   alert("Using Internet Explorer");
} else {
   alert("For other browsers");
}

//-->
</script>

I'd say it would be better to do it this way, because if a code doesn't work in FireFox it probably doesn't work in any other browser besides IE anyway.

I always use document.all..

<script type="text/javascript">
<!--

if(document.all){
Code for IE
}
else{
Code for Firefox
}

//-->
</script>

Errr...nooo. Browsers (FF, Opera etc) can be set to act like IE, only way to check would be to do object detection or other means, like user agent, or vendor

I figured that affected the userAgent property as well. And I know Opera can do that, but I've never seen any FF setting for it.

Nope, I believe user agent is harder to spoof (don't quote me on that), but anyway, appName is no good really, like I said, browsers like Opera, and Mozilla (One of them do. FF was wrong, but I believe there are extensions for it), and there are probably more of them about which have a setting to act like IE.
