         dump(window.navigator.appName);
         // prints "Navigator" to the console for NS6

Returns the version of the browser.

Note: The window.navigator.userAgent property also contains the version number (example: "Mozilla/5.0 (Windows; U; Win98; en-US; rv:0.9.2) Gecko/20010725 Netscape 6/6.1"), but you should be aware of how easy it is to change the user agent string and "spoof" other browsers, platforms, or user agents, and also how cavalier the browser vendor themselves are with these properties. The window.navigator.appVersion and window.navigator.userAgent properties are quite often used in "browser sniffing" code: scripts that attempt to find out what kind of browser you are using and adjust pages accordingly.

         if ( navigator.appVersion.charAt(0) == "5" ) { 
             // browser is putatively a v5 browser
         }

Returns a string representing the platform of the browser.

Note (Mozilla): Unless your code is privileged (chrome or at least has the UniversalBrowserRead privilege), it may get the value of the general.platform.override preference instead of the true platform.

Returns the user agent string for the current browser.

Note: Browser identification based on detecting the user agent string is unreliable and is not recommended, as the user agent string is user configurable.

• Mozilla Suite and Firefox can use the preference "general.useragent.override" in about:config. Some Firefox extensions or multi-bar do that.
• Opera 6+ allows users to set the browser identification string via a menu
• Microsoft Internet Explorer uses the Windows registry
• Safari and iCab allow users to change the browser user agent string to predefined Internet Explorer or Netscape strings via a menu.
