if you use adblock this way, you will block any link that has the string mid or mp3 etc in it. you won't be able to go to (for example) www.midday.com and you won't be able to download mp3's from a link.

this is a better way to block embedded audio (or embedded anything):
put this in you userContent.css file:

/* block embedded sounds */
embed[src*=".mid"] { display: none !important }
embed[src*=".mp2"] { display: none !important }
embed[src*=".mp3"] { display: none !important }
embed[src*=".mp4"] { display: none !important }
embed[src*=".wav"] { display: none !important }
embed[src*=".wma"] { display: none !important }

(on windows, you can find that here: C:\Documents and Settings\Administrator\Application Data\Mozilla\Firefox\Profiles\xxxxxx.default\chrome\userContent.css)
(you have to create that file, it won't be there if you haven't already)
