"Clear cache" Note: In order to be sure you are seeing the latest stream, or to speed up your internet browser, it is often a good idea to 'clear' your browser's internet surfing cache of old temporary internet files. To do this, go to your browser's Settings panel (normally top right of your page). Look for the History tab, then the 'clear browsing data' option and then select the option to ''empty the cache' and press the 'clear browsing data' tab to perform the task. In Firefox, Settings are labelled as 'Options' in the top left menu. Internet Explorer calls it 'Internet Options' and you can see the 'browsing history' info on the General tab.
