Firefox plugins for audio files
I've just come from a website that had mpeg and x-aiff audio files, neither of which Firefox would play. I got the "missing plugins" banner, but when I clicked on install I was told nothing suitable was available.
I was able to play the files, by downloading with Download Helper and playing in Rhythmbox, but surely there should be some plugin? I've tried a yum search, but nothing obvious showed up, nor was Google helpful.
