1. Hit Control+Shift+Esc to open the Windows Task Manager.
2. Click the Processes tab.
3. Find the plugin container and kill it.
This might make Firefox responsive again without having to kill the browser. Flash and other plugins can sometimes choke Firefox so killing the plugin container can be a huge timesaver.
