This error message means that the flash-plugin is recently dead.
The firefox/nspluginwrapper combination support windowless flash plugin, but the windowless flash can crash as well as the windowed one and when this happens (very often) you'll see this message.
It has nothing to do with the windowless mode, it's just a flash crash.
