Boy, did that surprise the heck out of me. I never worry about keeping my speakers turned up when going to google.com

Apparently this is overwhelming the Firefox support forums and chat lines:

CoolPreviews, an addon for Firefox, caused the PacMan music to play even when the user wasn't viewing google.com. They've released an update that fixes the issue.

Bad move by google, really. Start on a button click is one thing but auto-starting something that makes a bunch of noise on a page that has always been totally silent is really dumb.

Google doesn't autostart anything, it's a FireFox extension (Cool Previews) that loads the page in the background that causes the trouble. I suggest reading up on the real story before you start labeling things as "bad moves" and "really dumb".

Actually, the sound does autostart when you load the page. But the playing sound in the background issue is related to the extension.

My browser is 'clean', there are no extensions or plug-ins installed besides the 'closed tabs button' and greasemonkey.

Welcome to HN by the way.
