I am trying to give a flash application access to accessibility features. The plug in lives in Macintosh HD > Library > Internet Plug-ins. I cannot drag and drop this into the Security & Privacy > Privacy > Accessibility. Adding firefox app doesnt seem to work even though the plug in seems like it should be a child process. In activity monitor when the particular flash app is running the process name is "Firefox Plugin Process (Shockwave Flash)".
How do I enable this? How can I add items in the Accessibility menu without having to drag and drop?
Using OS X Mavericks 10.9.
