Warning: The information from the Navigator object is misleading and should not be used to detect browser versions because: Navigator data can be changed by the browser Consumer browser can not report later than the browser published new operating system browser detection

Because navigator can mislead browser detection, object detection can be used to sniff different browsers.

Because different browsers support different objects, you can use objects to detect browsers. For example, because only opera supports the attribute "Window.opera", you can identify opera accordingly.

Example: if (Window.opera) {... some action ...}
