Check and update

  1. See your version. Open Menu > Help > About Firefox.
  2. Update. Open the About Firefox window. Firefox downloads the update and shows a Restart to Update button.
  3. If the update is stuck. Restart the computer and try again; a pending Windows restart or a second copy of the browser running in the background is the usual cause.
