</html>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 browser users. Some browsers will recognize errors on test sites. The browser cannot report new operating systems released later than the browser.
Browser detection
Due to navigator Can mislead browser detection, and can be used to sniff different browsers using object detection.
Since different browsers support different objects, you can use objects to detect browsers. For example, you can identify Opera because only Opera supports the property "window.opera".
Example: if (window.opera) {...some action...}
