On a Mac running OS X, as the initial installer of Firefox and primary admin user, when Firefox has an update, it will download and prompt to restart to install the update (although this only happens when I query "About Firefox"). I have a second user who has admin capability, but querying "About Firefox" will only show that "Updates available at https://...". This requires that the user login as the primary admin user to get the update. How can I set Firefox up so that any admin user can get the updates installed?
