List of Navigator Attributes by Browser and Operating System

As a web designer, I have had to test my sites in many different browsers. My pages tend to be customized for each browser, and over time, I've accumulated a list of navigator attributes that I test for. Sometimes I redirect a browser based on what operating system they use (navigator.platform) other times by language (navigator.systemLangauge, which isn't supported by Firefox). So, here's a table of the attributes for which I've tested. I believe that some people would find it useeful. Note that these were obtained in different operating systems (usually virtual machines). Internet Explorer 2 is not included in the results because it did not support scripting:

You may have noticed that Opera 8.5 identifies itself as Internet Explorer 6.0 by default, although this can be changed by going to Tools → Preferences → Advanced and selecting another option from the Browser Identification drop-down menu. That browser never ceases to impress me. You may have also noticed that almost every browser includes the word Mozilla in its application version information. It has nothing to do with Firefox. This is an old spoof used by browsers to pretend that they were Netscape Navigator.

As you may have guessed from the above answers, detecting Netscape Navigator is a bit tricky today! It makes me wonder whether the usage share of Netscape Navigator is under-estimated by HitsLink!

To test this out in your own browser, type the following code into a text file and save it with a .html or .htm extension: <html>    <head>       <script type='text/javascript'>          document.write("User agent: " + navigator.userAgent + "<br/>");          document.write("App name: " + navigator.appName + "<br/>");          document.write("App version: " + navigator.appVersion);       </script>    </head>    <body>    </body> </html>
