Plugin Crash Logs on Mac OS X?

I'm developing a netscape plugin and for some reasons it crashes.  I'm not able to find the crash logs though I've made 
$  defaults write org.mozilla. firefox OSCrashReporter -bool true

I tried even deleting the crashreporter.app, still I could not find the plugin-container crash logs.

Is there any-ways to dump the crashes on my local computer.  I know about:crashes would show the crashed logs, but I need the logs on Mac OS X crash format.
