I have installed Firefox 26 for Windows. I then installed some add-ons for all users by copying the XPI files into the \mozilla firefox\browser\extensions folder. For the user that I installed them under they are enabled. When I then log out and back in as any other user they show as disabled. I have played around with various settings in my .js files and I cant get anything to work. Why do you make the global installation of add-ons so difficult? Surely for enterprise deployment this is a required configuration. I am also unable to set my homepage in the same way despite following many articles on this forum.
