Listening difficulties

All right, what gives? Why did those two morons–ahem, gentlemen–change the on-line audio delivery system? I cannot persuade Firefox (3.5.3) to accept the audio. The little red window comes up, says that it’s “Done”, and that’s all I get. Yes, I downloaded Adobe 10. Yes, I told Firefox to permit pop-ups &c. Nothin’.

Internet Explorer accepts it without a blink, but who wants to open I.E. when I already have twenty Firefox tabs open & a-runnin’?

Suggestions, anyone?
