There are several benefits to updating your browser to the latest version. The most notable benefit is ensuring that you have the browser with the highest level of security fixes available, plus any additional fixes to compatibility issues present in older browsers which can adversely affect the sites you visit.
Generally speaking, browsers including Chrome, Firefox and Safari automatically update to the latest version. However, with Internet Explorer, only the very latest versions have automatic updates enabled.
To find out which version of Internet Explorer you have, click on the Tools icon as shown and then click "About Internet Explorer". This will reveal your version number.
