Install Add-ons for all users

Installing Firefox add-ons for all users can be a great way to reduce your workload and provide all users that use a computer with the same basic extensions that can add functionality, privacy and security. Even greater is the fact that those add-ons are also available to all future users with an account on the system.

You need to use the command line in Windows to install a Firefox add-on for all current and future users. The basic command is firefox –install–global–extension “full path to the xpi file”. The only difference between installing an add-on for the current user and for all users is that you have to download the xpi file for the latter.

If you wanted to install addon.xpi you would use the command firefox –install–global–extension c:\addon-xpi if that file would be on the c: root.
