I have an Ubuntu desktop set up in a retail environment. I would like to restrict access to firefox. So that users must type in a password to run it. I tried changing permissions on the binary so that it did not have world access, but each time the update runs, those permissions get reset to world access.
Its convenient to have it available but its not strictly necessary for the software that the machine must run. so if it isn't possible to restrict it, then I can uninstall it if it won't impact functioning of the system. Would it impact the system to uninstall it?
