Shockwave Flash plugin hangs Firefox, how do I stop this?


The shockwave flash plugin consistantly hangs firefox with everything Youtube related. I can't watch any videos of that format (which seems to be most videos.) Whenever this happens, I have to end the plugin_container process from the task manager. How can I stop this from happening? Is this issue being addressed? If this continues, I will be forced to switch away from Firefox permanantly.
