How can I refresh a web site that I use often but it also changes its content frequently. Where is the refresh icon?

Firefox 4 and later use a combined Stop/Reload/Go button that is positioned at the right end of the location bar.<br /> During the page load process it shows as a Stop button and after the loading has finished the button is changed to a Reload button.<br /> If you type in the location bar then that button becomes a Go button.<br /> Middle-click the Reload button to duplicate the current tab to a new tab.<br /> ---- *https://support.mozilla.com/kb/common-questions-after-updating-firefox
