Mozilla Firefox is a web browser. Mozilla Firefox can be run as a Windows Service using FireDaemon Pro, which allows you to have the application start automatically at boot prior to login, start multiple instances of the application and more. This HOWTO will show you how to set it up. You can also use Fusion to manage FireDaemon and other Windows services via a web browser.

Mozilla Firefox Setup Under FireDaemon

Download the latest version of Mozilla Firefox from the Firefox website.

Install Mozilla Firefox. By default it is installed to C:\Program Files (x86)\Mozilla Firefox.

Start the application manually first to generate your profile.

Download and install FireDaemon Pro into the directory of your choice, typically C:\Program Files\FireDaemon.

Next start the FireDaemon GUI from the desktop shortcut. Click on the "Create a new service definition" button in the toolbar (or type Ctrl+N) and enter the information into the fields as you see below. Adjust the paths to suit your installation. Note that no parameters are required.

  • Executable: The path to your firefox.exe file. For the purposes of this HOWTO, the path is C:\Program Files (x86)\Mozilla Firefox\firefox.exe.
  • Working Directory: The directory containing your firefox.exe file. For the purposes of this HOWTO, the path is C:\Program Files (x86)\Mozilla Firefox
  • Parameters: None. Leave this field blank.

Now click on the Settings tab. If you DON'T want to see Mozilla Firefox running, uncheck the Interact with Desktop check box & select “Hidden” from the “Show Window” dropdown. You must run Mozilla Firefox as the user you installed it as. In the Logon Account field type your username (e.g. Administrator) and then enter the user's password twice in the Password and Confirm fields. You can change the Process Priority to allocate more CPU time to Firefox or specify which CPU or core Mozilla Firefox will run on (in the case of multi-processor, hyperthreaded or multi-core CPUs). You must change the "Job Type" to "Global Job", otherwise when Mozilla Firefox is restarted, the child processes will not be terminated properly.

Now click on the Lifecycle tab. Uncheck Graceful Shutdown as leaving it checked might delay the shutdown of Mozilla Firefox.


Now click on the OK button to install and start Mozilla Firefox!
