Firefox Addon Check


I saw a site that check if i have a ad-block addon in firefox but cant find something like that on google or similar.
I know it exist php scripts that show what browser I have

<?php$useragent = $_SERVER[‘HTTP_USER_AGENT’];if (preg_match(‘|MSIE ([0-9].[0-9]{1,2})|’,$useragent,$matched)) { $browser_version=$matched[1]; $browser = ‘IE’;} elseif (preg_match( ‘|Opera ([0-9].[0-9]{1,2})|’,$useragent,$matched)) { $browser_version=$matched[1]; $browser = ‘Opera’;} elseif(preg_match(‘|Firefox/([0-9\.]+)|’,$useragent,$matched)) { $browser_version=$matched[1]; $browser = ‘Firefox’;} elseif(preg_match(‘|Safari/([0-9\.]+)|’,$useragent,$matched)) { $browser_version=$matched[1]; $browser = ‘Safari’;} else { // browser not recognized! $browser_version = 0; $browser= ‘other’;}print “browser: $browser $browser_version”;?>
Please help


There's no real way to detect a popup blocker in PHP but it is pretty easy in JavaScript.

<script type="text/JavaScript" language="JavaScript"> var mine = window.open('','','width=1,height=1,left=0,top=0,scrollbars=no'); if(mine) var popUpsBlocked = false else var popUpsBlocked = true mine.close()</script>

Just insert that in the HEAD of your code and wether or not their browser blocks popups will be stored in the popUpsBlocked variable.


Lol i tought it was php they used, but now I think its javascript, they used code like this
in a file advertisement.js

document.write('<style type="text/css"> .hideitblock2 {visibility:invisible;display:none;}</style>');
in the index file
<script type="text/javascript" src="advertisement.js"></script><noscript><style type="text/css"> .hideitblock2 {visibility:invisible!important;display:none!important;}</style></noscript><table style="position:absolute;top:0px;left:0px;background-color:#000000;" width="100%" height="100%"><td width="100%" height="100%"><h1 align="center"><font color="ff0000">Please Disable Ad-Block or Add Instantz.net To Your Whitelist To View This Website Properly.</h1></td></table>
