- Detecting the plug - in version via the object element is more precise than using the plugins collection item ' s description :
a . Both release and build numbers can be detected
b . Avoid wrong descriptions by corrupt installers provided by Adobe
c . Avoid wrong descriptions by multiple Flash Player entries in the plugin Array , caused by incorrect browser imports
- Disadvantage of this method is that it depends on the availability of the DOM , while the plugins collection is immediately available
