I've tried to install Adobe Flash Player numerous times. I go to their web site and download the installer. I then run it as an administrator and it says that it installed fine. However, when I get into Firefox V30.0 and go to Add-Ins Manager, it's not listed. I've tried uninstalling the add-in from "Add and Remove Programs" from Control Panel and install it again. I've tried uninstalling Firefox and downloading a new copy and then installing Adobe Flash Player again. I've re-booted my computer numerous times. Nothing works.
