Get Adobe Reader version using Javascript

Question

What is the best way to get the adobe reader version in Javascript.

Answer 1

I have found this but it only works in Internet Explorer

 function CheckAdobeVersion() {


        var isInstalled = false;
        var version = null;
        if (window.ActiveXObject) {
            var control = null;
            try {
                // AcroPDF.PDF is used by version 7 and later
                control = new ActiveXObject('AcroPDF.PDF');
            } catch (e) {
                // Do nothing
            }
            if (!control) {
                try {
                    // PDF.PdfCtrl is used by version 6 and earlier
                    control = new ActiveXObject('PDF.PdfCtrl');
                } catch (e) {
                    return;
                }
            }
            if (control) {
                isInstalled = true;
                version = control.GetVersions().split(',');
                version = version[0].split('=');
                version = parseFloat(version[1]);
                return version;
            }
        } else {
            // Check navigator.plugins for "Adobe Acrobat" or "Adobe PDF Plug-in"*
        }
    }    

Any ideas how i could get it to work in Firefox or chrome?
