If you start using Firefox 3 with Flash, odds are good that you’ll experience Firefox crashing every few minutes while loading Flash. It seems Pulseaudio (Hardy’s new sound system) is triggering a bug in Flashplayer, which causes Firefox to crash. Since Flash is closed-source software, there’s no chance Ubuntu is able to fix the problem in time for Hardy Heron’s release.
