Does anyone else have issues with audio dropping out on Flash movies when using Fire Fox 3 for an extended period of time? When it first started to happen I thought my machine was out of memory and just needed a reboot. The reboot would fix the issue but only for a short period of time. So, I did a bit of research on Google and found a solution that works for my machine.
Go to: Tools >> Add-ons >>
Then disable the Shockwave Flash plugin
Next enable the Shockwave Flash plugin The flash audio issues should now be fixed.
I really hope the next version of Fire Fox will address this issue.
