Player not showing in Firefox 3

“Endless buffering” in Firefox on Windows
Update: Apparently, Flash 10 beta has fixed this issue.
The following combination can cause Audio Player to stop functioning:
When you have 16 or more players open, the mp3 files load but never start so it looks like the player is stuck in “endless buffering” mode. Once this happens, you have to restart Firefox to get it back to normal (until you load another 16 players at once that is).
Solution:
Until Adobe (or Mozilla, I’m not sure who’s to blame) fixes this, all you can do is try to limit the number of players you embed on one page. If you are going to use multiple players on one page, make sure you limit that number to something reasonable (I would say 10 at the most).
