Programa Mozilla Firefox

yes, but how do I add the camera icon to the list of editable functions? OS X Yosemite version 10.10.5 only allows for the following function to be editted: Diagnostics&Usage, Accessibility, Facebook, Reminders, Calendars, Contacts, and Location Services (see picture below). Ultimately, I want to configure particular apps to have/not have access to my audio and camera and there is not a way to easily modify this in the System Preference > Security tab. I have seen youtube videos describing making changes within "terminal" ... but I am not a coder and it seems like this is an elementary function that should already be built into OS X Yosemite, like it is in the Cantalina/newer macbooks... Am I missing something?
