In Options under General tab there is a box for setting Home Page, i click Restore to Default button to set the Mozilla Firefox Start Page as the Home Page and close the window. After that when i open new window i don't see the Home Page that i had set it is the previously set Home Page. And also when i select Google as the Default Search Engine in Select tab and delete the Oursurfing from the list and close the window and restart the window, all the changed settings remain same.
