For info only, this is old skool, useful really only if you wanted to check for IE

Before it was possible to use appName, but both Mozilla and Safari both return Netscape which is why you cant really use it now.

the navigator object is a throwback from Netscape Navigator days I believe hence the use of that keyword.

simple test I used. This is for information only, it is not something you should be using. As I said before, only handy if you want to check for MSIE only.

So your best bet to identify individual browsers nowadays is to use userAgent and which euzuro has given you the answer to your question.

You can use the navigator object to determine other things as well like version (use indexOf) and os. A sample function can be found here http://www.quirksmode.org/js/detect.html
