Javascript browser detecttion with FF4

Question

Hi,
The following code works fine across all browsers except for FF4 ( worked in FF3).
What can I do now to fix the javsscript code below???
//Browser detections and OS
//Browser raw
function BrowserRaw()
var browser=navigator.appName;
var version=navigator.appVersion;
var r = browser +' '+ version;
return r;
//http://www.quirksmode.org/js/detect.html
var BrowserDetect = {
init: function () {
this.browser = this.searchString(this.dataBrowser) || "unknown1";
this.version = this.searchVersion(navigator.userAgent) || this.searchVersion(navigator.appVersion) || "-1";
this.OS = this.searchString(this.dataOS) || "unknown2";
searchString: function (data) {
for (var i=0;i<data.length;i++)
var dataString = data[i].string;
var dataProp = data[i].prop;
this.versionSearchString = data[i].versionSearch || data[i].identity;
if (dataString)
if (dataString.indexOf(data[i].subString) != -1)
{return data[i].identity;}
else
{return 'unknown3';}
else if (dataProp)
{return data[i].identity;}
else
{return 'unknown4';}
searchVersion: function (dataString) {
var index = dataString.indexOf(this.versionSearchString);
if (index !== -1)
{return parseFloat(dataString.substring(index+this.versionSearchString.length+1));}
else
{return 'unknown5';}
dataBrowser: [

You can use [Google Web Toolkit|http://code.google.com/webtoolkit/overview.html].
It helps to write any Client-side JavaScript application on Java. And, of course, CSS and XML (for XPath) support is present.
You don't need Java Applet if you aren't accessing any hard devices on the client mashine.
So, if your XPath is on the Server GWT is your choice.
