Tiago: upstream (mozilla) has made it very clear they won't be changing anything on their end. All the bugs you linked are closed as WONTFIX.
This is up to the distribution to solve: either add pulseaudio to lubuntu, or compile firefox with alsa support (and maybe patch it if Mozilla drops alsa support completely in the future). Simon: any progress on this? Anything we can help with?
