Thanks for the tips guys. I was able to do it by:
1) Uninstalling Firefox Flash player (https://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html). 2) Install NPAPI debugger. 3) On Firefox, go to "Open menu -> Add-ons -> Shockwave Flash (click 'Options' or 'More')" and then *uncheck* "Block dangerous and intrusive Flash content". -- Sent from: http://apache-flex-development.2333347.n4.nabble.com/
