I have installed the debug flash player for my mac, as explained in various articles. The problem I have is that the player doesn't show the errors - which I as a tester need to see. Version check tells me that I have MAC 10,2,153,1 both in Chrome 11.0.696.71 and Firefox 4.0.1. In Chrome I have disabled the built-in Flash Player Plugin for Chrome.plugin and enabled the debug plugin I installed. The only hint I have that something is wrong is that when I right-click on a flash content then the Debugger item is inactive in the context menu. As I have uninstalled and re-installed the plugin many times in the last months, I am really clueless now what the problem could be. I would be thankful for any hint.
Check your mm.cfg file for SuppressDebuggerExceptionDialogs=1 which suppresses the exception dialogs, as the name implies. I had this in my mm.cfg file and have no idea how it got there.
Setting the value to 0 fixed it.
On a Mac the mm.cfg files is at /Library/Application Support/Macromedia
