Firefox – Install with Add-ons installation disabled

by

The following process has been tested and confirmed as working with Firefox 11.1 and SCCM R3 on Windows XP x86, Windows 7 x86 and Windows x64.

It does the following tasks:

  • Install Firefox 11 silently
  • Configures Firefox to NOT allow add-on installation

With this setting enabled if I user tries to install an add-on they will see the following message:

Software installation has been disabled by your system administrator.

Firefox-DisableAddonInstalls

To automatically configure settings for all users you can create a ‘configuration file’ and enter in the required settings.
This article goes through the process of creating the configuration file (mozilla.cfg) and setting the proxy server settings.
