Java Applets and Firefox unresponsive Error message

I have a Java Applet. On IE, it works fine, On Firefox, Firefox frequently given a dialog box saying "The plugin is unresponsive/hung. Do you want to continue waiting for it or kill it?".

In order to troubleshoot, it would be useful to know how firefox detects that the plugin is unresponsive - has Firefox published this info anywhere?

I found this page - https://developer.mozilla.org/en-US/Add-ons/Plugins/Out_of_process_plugins/The_plugin_hang_detector

However this talks about killing the plugin & not giving this error message.
