No, it is not possible to install Firefox without the service. The only way to disable it is to follow the directions at What is the Mozilla Maintenance Service?

also you can confugure your update option. instruction are here in Update Firefox to the latest release article

It'd be really nice if they could add a command switch that didn't install the maintenance service. Now for mass corporate rollouts I'm forced to Run the Firefox installer and then a script that deletes the service and probably the scheduled task that's created..

Now, the service will only run when a Firefox update is being installed, and will kill itself after the update is installed. And there is no scheduled task (chrome does that, Firefox doesn't).

During installation of Firefox Setup 12.0.exe I copied the extracted files from the temp folder. Deleted the "maintenanceservice_installer.exe" file from the core folder and then installed with setup.exe /S to do silent install. Mozilla Maintenance Service did not install.

I know this is an old thread but the discussion is about Firefox Updates in a corporate environment.

Mozilla Firefox may not widely publicise it but there is a Firefox ESR that has a longer supported time between major upgrades and currently whilst we are now on the Firefox 15 Release and soon will upgrade to Firefox 16 the ESR at the moment is based on Firefox 10.

Enterprise users may wish to consider Firefox ESR if so see http://www.mozilla.org/en-US/firefox/organizations/

Block Mozilla Maintenance Service from installing by running the following command BEFORE you run the Firefox Setup X.X.X.exe installer:

• REG ADD HKLM\SOFTWARE\Mozilla\MaintenanceService /v Attempted /t REG_DWORD /d 1 /f
