Intrusive music now occurs when I open firefox. How do I stop it?

Question

I have been using Firefox for a long time, and now use it on Windows 8 with a 64 bit processor.
This morning, 28 January 2014, I found that when I opened Firefox, I heard unknown, intrusive, repetitious music that I could not stop, although it stopped itself when completed. Searching for a solution in the Help resoiurces, I failed to find one. I therefore uninstalled Firefox and reinstalled it. However, the music still comes on. I am at a loss as to what to do to remove it.

It sounds like an add or a game you had played.
