Make sure that Firefox is open. Click on the Firefox button located on the menu bar. You do not need to have a Firefox window open to update the browser.
With the About Firefox dialog box open, check to see if the browser has any outstanding updates for you to install. The dialog box shows that Firefox is up to date if there are no updates for the browser.
The browser downloads all updates automatically. When the dialog box announces that the updates are ready for installation, click on the Restart to Update button. Clicking on this button closes all open Firefox windows and restarts the browser.
If the browser does not completely download the updates or if you see the error message Update Failed, close Firefox. Download and reinstall the latest version of the browser by visiting the Mozilla Firefox website.
