DO NOT MIX command line options from different lines below (e.g. don't mix /S with /INI, etc.)
The account performing the installation will require administrative privileges to properly complete the installation.
This page applies only to the full installer and not the stub installer. If you want to perform a silent install you cannot do so with the stub installer and you must use the full installer. Full installers for Firefox can be found at http://www.mozilla.org/firefox/all/ (or for Firefox ESR at http://www.mozilla.org/firefox/organizations/all/ ).
Silent install (always installs into the default location. Use the "Configuration ini file" option below to set the install location and other install options):
<path to setup executable> -ms
<path to setup executable> /S
Configuration ini file:
<path to setup executable> [/INI=<full path to configuration ini file>]
When specifying a configuration ini file the installer will always run silently. When specifying a Configuration ini file other command line switches should not be specified and may have unexpected results
Configuration ini file syntax and available settings:
[Install] ; ; Remove the semicolon (;) to un-comment a line. ; ; The name of the directory where the application will be installed in the ; system's program files directory. The security ; context the installer is running in must have write access to the ; installation directory. Also, the directory must not exist or if it exists ; it must be a directory and not a file. If any of these conditions are not met ; the installer will abort the installation with an error level of 2. If this ; value is specified then InstallDirectoryPath will be ignored. ; InstallDirectoryName=Mozilla Firefox ; The full path to the directory to install the application. The security ; context the installer is running in must have write access to the ; installation directory. Also, the directory must not exist or if it exists ; it must be a directory and not a file. If any of these conditions are not met ; the installer will abort the installation with an error level of 2. ; InstallDirectoryPath=c:\firefox\ ; By default all of the following shortcuts are created. To prevent the ; creation of a shortcut specify false for the shortcut you don't want created. ; Create a shortcut for the application in the current user's QuickLaunch ; directory. ; QuickLaunchShortcut=false ; Create a shortcut for the application on the taskbar. ; TaskbarShortcut=false ; Create a shortcut for the application on the desktop. This will create the ; shortcut in the All Users Desktop directory and if that fails this will ; attempt to create the shortcuts in the current user's Start Menu directory. ; DesktopShortcut=false ; Create shortcuts for the application in the Start Menu. This will create the ; shortcuts in the All Users Start Menu directory and if that fails this will ; attempt to create the shortcuts in the current user's Start Menu directory. ; StartMenuShortcuts=false ; The directory name to use for the StartMenu folder (not available with ; Firefox 4.0 and above - see note below). ; note: if StartMenuShortcuts=false is specified then this will be ignored. ; StartMenuDirectoryName=Mozilla Firefox ; The MozillaMaintenance service is used for silent updates and may be used ; for other maintenance related tasks. It is an optional component. ; This option can be used in Firefox 16 or later to skip installing the service. ; MaintenanceService=false ; Starts with Firefox 60, it's possible to mark all or some of the extensions ; bundled within a partner distribution as optional. ; Set this option to false to opt-out installtion of any optional extensions. ; OptionalExtensions=false
As of Firefox 4.0 StartMenuDirectoryName is ignored due to the removal of the start menu directory for Firefox and the creation of a start menu shortcut in the root of the start menu (see bug 598779).
