DISABLE COOL PREVIEWS EVERYBODY! These sounds freaked me out. I re-installed Firefox but still awful "Mario music" followed by incessant sirens!!! :( How BIZARRE!!! DISABLED COOL PREVIEWS AS SUGGESTED AND SWEET SILENCE! Thanks to whoever spotted that! :)

Thank you very very much! :D It annoyed me so much. Have scanned my pc for spyware or a virus. But nothing happened.

Now the sound is gone :D Thanks

It's Pac-Man's 30th Birthday today, and Google's homepage is a playable Pac-Man game around the Google logo. My boyfriend had the same problem, then I went to Google and was like Hey, it's Pac-Man! And then the siren started. He plays fine on my laptop, but for some reason the music is stuck on his computer.

All you have to do is disable the "Cool Previews" add on for firefox. Go to the "Tools" link at the top of the browser, go down to "Add Ons", go to the "Cool Previews", click "Disable". Then restart firefox and it should be fine!

I had the same problem, and also for me disabling COOL PREVIEWS did the trick of finally shutting that incessant fracking noise up
