Hvilke browsere er kompitable med dette script?

Hej, er igang med et it case, og ville lige høre hvilke browsere der er kompitable med dette script:


<SCRIPT LANGUAGE=JavaScript1.1>
<!--
var MM_contentVersion = 6;
var plugin = (navigator.mimeTypes && navigator.mimeTypes["application/x-shockwave-flash"]) ? navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin : 0;
if ( plugin ) {
        var words = navigator.plugins["Shockwave Flash"].description.split(" ");
        for (var i = 0; i < words.length; ++i)
        {
        if (isNaN(parseInt(words[i])))
        continue;
        var MM_PluginVersion = words[i];
        }
    var MM_FlashCanPlay = MM_PluginVersion >= MM_contentVersion;
}
else if (navigator.userAgent && navigator.userAgent.indexOf("MSIE")>=0
  && (navigator.appVersion.indexOf("Win") != -1)) {
    document.write('<SCR' + 'IPT LANGUAGE=VBScript\> \n'); //FS hide this from IE4.5 Mac by splitting the tag
    document.write('on error resume next \n');
    document.write('MM_FlashCanPlay = ( IsObject(CreateObject("ShockwaveFlash.ShockwaveFlash." & MM_contentVersion)))\n');
    document.write('</SCR' + 'IPT\> \n');
}
if ( MM_FlashCanPlay ) {
    window.location.replace("http://www.kirupa.com/flash.htm");
} else{
    window.location.replace("http://www.kirupa.com/noflash.htm");
}
