While working suddenly firefox browser became hang. Even there was no way to go to another tab. The program was not responding. So I solved the problem in following ways:
1. Click on Finder icon in taskbar
2. Go to System->applications->Utilities
3. Click on Activity Monitor and select on the tasks which are not responding
4. click ‘Quit process’ and finally close the window.
