Sorry you had a bad experience. It does work in Firefox, although there are bugs in the current stable version (which is why we are encouraging Chrome). Specifically, two nasty ones are audio echo (https://bugzilla.mozilla.org/show_bug.cgi?id=916331) and audio latency (up to 10 seconds: https://bugzilla.mozilla.org/show_bug.cgi?id=785584).

What version of Firefox are you using? What OS?
