about:plugins, Plugging into Plug-ins

Each plug-in installed on your computer is available to Firefox. You might feel that you are installing plug-ins into your browser, but in fact they are at the computer level. That is, after a plug-in is installed, it remains available to all users and programs (see Figure 9.8).

Figure 9.8. All plug-ins installed on the computer are listed in about:plugins. Plug-ins are specific to a computer, not a user, profile, or Firefox.
