Mozilla Firefox is a popular web browser, but it can sometimes be frustrating when it opens automatically every time you start your computer. Whether you prefer a faster startup or want to prevent unnecessary programs from running in the background, stopping Firefox from launching at startup is an easy task. Below are three effective methods to disable Firefox from opening automatically on Windows 11.

1. Disable Firefox from Startup via Task Manager

The Task Manager in Windows 11 allows you to manage which programs run when your PC boots up. You can use this tool to stop Firefox from opening automatically.

Steps to Disable Firefox from Startup:

  1. Right-click the Start button and select Task Manager or press Ctrl + Shift + Esc.
  2. In the Task Manager window, go to the Startup tab.
  3. Locate Mozilla Firefox in the list of startup programs.
  4. Right-click on Firefox and select Disable.
  5. Restart your computer to ensure the changes take effect.

Once you disable Firefox in the Task Manager, it will no longer open automatically when you start your PC.

2. Adjust Firefox’s Settings to Prevent Startup

Firefox offers a built-in setting that allows you to control whether it opens upon startup. By changing this setting, you can stop Firefox from launching when Windows 11 starts.

Steps to Disable Firefox at Startup:

  1. Open Firefox.
  2. Click on the three horizontal lines (hamburger menu) in the top-right corner and choose Settings.
  3. In the Settings menu, scroll down to the General section.
  4. Under the Startup subsection, uncheck the box labeled Open tabs from the previous session or Open Firefox windows and tabs from the previous session.
  5. Close the settings window and restart your computer.

This option prevents Firefox from automatically restoring your previous session, which is often the cause of it launching at startup.

3. Use the Windows 11 Settings to Manage Startup Apps

Windows 11 also lets you control startup programs through the Settings app. This method is simple and effective, especially if you’re trying to reduce the number of background applications running on your system.

Steps to Disable Firefox from Startup via Windows Settings:

  1. Open the Settings app by pressing Windows + I or by clicking on the Start menu and selecting Settings.
  2. In the Settings menu, go to Apps and select Startup.
  3. Scroll down to find Mozilla Firefox in the list of apps.
  4. Toggle the switch next to Mozilla Firefox to Off.
  5. Restart your computer to apply the changes.

After disabling Firefox here, the browser will no longer automatically launch when you start your PC.

Firefox might open automatically after a restart because of a setting that restores previous browsing sessions or a startup configuration in Windows 11. To prevent this, you can change Firefox’s startup behavior in the browser settings, disable it in Task Manager, or turn it off in Windows Startup settings.
