These appear when you have the debugger version of Flash Player installed and you run a SWF with errors in the code that are not handled correctly, either through appropriate logic, try..catch blocks, or the correct event listeners. But what if you don't want them?
Up until now, you've really only been left with uninstalling the debugger player and replacing it with a release build - that or simply using a different browser with the release build already installed for it (testing with a different browser). But I'm here today to tell you there's another option.
There's an unsupported, undocumented mm.cfg file option called SuppressDebuggerExceptionDialogs which, when set to 1 (the default is 0), will prevent those dialogs from appearing in the debugger player.
Throw that into your mm.cfg and start browsing the web without fear of obnoxious error dialogs from lousy SWFs.
