Hi everyone

Is there anything i can do to block and stop firefox browsers viewing my site so that only Internet Explorer can view it?

If not is there any software that protects my site content against firefox?

Thanks

You can use the $_SERVER['HTTP_USER_AGENT'] variable to inspect the user agent string sent with the http request - I do this to give out alternate stylesheets to different browsers.

Can I ask why you want to exclude a sizeable proportion of your potential viewers? If people come across your site in FF they are likely to disappear ad never return. In what way are you 'protecting' your content - it's not as if Firefox will damage it or anything?!

I will echo that sentiment. I'm very curious.

The reason i want to protect my content is because my friend has been trying to get pictures from my site fro ages and he found a way evuntuall usin firefox and i was wanting to put a block on firefox users for a laugh

So how exactly do you do this?

Errm...it's the same for IE. Anyone can steal your pictures. It's not exactly hard. All the methods I have seen for both IE and FF all have flaws or simple things that can be done by the user to disable them (well, most of the time).

What pictures are these? Are they graphics as part of your layout? are they pictures you want people to pay for?

If they are part of your layout or just sitting there as images on your site, there's no way to stop people getting the images since the browser has to have a copy in order to display it.

For pictures you want to protect, you can put in place a login system such that only registered users can view the pictures. Using PHP this will work across all browsers too.

Blocking all firefox users just cos your friend happens to use it is plain daft IMO...

I know it sounds daft but my site if just a personal one i made and i just want to block firefox browsers from viewing it but my sites server doesnt support PHP,Perl or ASP so i cant use these but isint there like a HTML script that checks what browser you have and blocks the one i want like Fire Fox?

Nope. HTML is a markup language, not a scripting language.

Here is a javascript sample to redirect the user (you can do anything that you want) that don't have microsoft Internet Explorer.

HTML Code:

<html>
<head>
<title>test browser</title>
<script language="javascript" type="text/javascript">
var mybrowser = navigator.userAgent.toLowerCase();

if ( mybrowser.indexOf('msie') == -1)
{
    location.href = "http://www.disney.com"; //redirect the user to another page
}
</script>
</head>
<body>
your page
</body>
</html>

In any case the users can disable javascript or change useragent (yes, it can be done) and have access to your page even with a non MS IE browser.
Anyone can take your images if those are available from the webserver,
also embedding the images within flash movies or particular plugins will not be enough.

uhm a useless thread ?
