If you leave Firefox open when Windows shuts down, Firefox may automatically re-open with your previously opened tabs the next time you start Windows. Here's how to disable the feature.

Prevent Firefox from starting automatically

  1. In the address bar, enter about:config.
  2. The "This might void your warranty!" warning page will appear. Click I accept the risk! to continue to the about:config page.
  3. Search for toolkit.winRegisterApplicationRestart and double-click on it to set its value to false.
  4. No need to restart Firefox, the changes take effect immediately.
Windows Restart Manager: Starting apps automatically upon restart is a feature on Windows computers. To learn more about it, see this Microsoft article.
