  1. Download the latest Desktop version of Firefox from this page and save the setup file to your computer.
  2. Now, go ahead and reinstall Firefox:
    1. Double-click the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
