My husband was attempting to update itunes so that he could add music to his ipad. He had connected his ipad to our PC and tried to download some music. However, he was told he had to update itunes. When he proceeded to access the update, we lost our internet connection. I assume Firefox crashed. He was able to restore the connection, but it took quite a lot of effort. How could we have prevented the crash and how could we have restored it more quickly? itunes seems to play havoc with our PC every time we have to make an adjustment. Why is this?

  Thank you for your help.
