My cumputer makes pacman an siren noises when firefox is open

I disabled Cool Previews & the noise/sound stopped.

This is something to do with Google, idk how to fix it. Check the google homepage which has a mini Pacman game on it

I disabled cool previews and it worked thanks! The sounds started when i played a zelda video on newgrounds. Anyway, does anyone know the reason do this? is it a google thing, because i didn't touch google till i had this problem.

Thanks

I'm getting the same thing, but I don't know much about computers, can someone help me disable Cool Previews?

never mind, played around with the system and got it sorted out.

 i disabled cool preview too and the sound was gone. It is some sort of siren sound.

Disabling Cool Previews also stopped the same siren noise on my computer. Boy, is that annoying!! Unfortunately, I used Cool Previews all the time.

Firefox techs -- please debug this ASAP!!!
