I followed the advice to disable Cool Previews and the Pac Man sounds have gone away.

I have cool previews and disabled it BUT IT WON'T MAKE THE SOUNDS STOP!

thanks it is gone now

Add me as another user who uninstalled CoolPreviews and won't ever install it again!

Thanks for the fix.... I removed cool preview and now the sound is gone.

yeah, disabling Cool Previews worked.

I think Cool Iris just lost a lot of users today.

For those of you who want a step by step: -open your firefox browser -ignore the music ; ) -click on Tools at the top -click on Add-Ons -find Cool Preview or Cool Iris -click Disable (or Uninstall) -restart your firefox browser -smile in relief at the beautiful silence

where is cool previews? I can't stop this stupid pac man noise!

Thanks, It worked ,

Come on people... Because of the Droodle about Pacman today it's playing the music. Much better even: The Droodle is playable! This is the most brilliant Droodle from Google ever!

I think CoolIris just did this to get everyone to update CoolPreviews. If you uninstall it go to http://www.coolpreviews.com and reinstall it, the annoying Pacman sounds go away and CoolPreviews works with the new configuration of Google images (hovering over an image to make it open).

Disabling worked, thank you! Hope they fix it because I really like Cool Previews...

Install Chromium and don't use useless extensions.

How do disable or uninstall Cool Iris add on? Thanks
