Why would Facebook come up while visiting Pandora?

I have noticed that a Facebook account that I opened has been hacked and I cannot seem to change the password or do anything to overcome this hack so hopefully it will be deleted when it was set for deletion.(that I was able to do.) I was listening to Pandora and this came up in my search bar, javascript:onTunerEvent('onChangeDefaultSkinRequest', 'default');onTunerEvent('FacebookConnector_hideLikeContainer');
Does anyone uderstand this? When I clicked refresh, I was taken back to Pandora and music continued to play. Can Java programs track my movements while connected to the internet? I hope I dont sound paranoid but im getting annoyed to the point of purchasing a new laptop. Any help is appreciated. Thanks a bunch.
