Right-clicking a video after it begins playing leads, sooner or later, to a crash, possibly accelerated by using the mplayerplug-in "stop" button, and right-clicking again. Reproducible: Always Steps to Reproduce: 1.) Start playing a video on http://www.stage6.com 2.) Right-click somewhere in the video 3.) Hit the stop button 4.) Right-click until crashes Actual Results: Debug info from Firefox: [00000393] main audio output debug: audio output is starving (39289), playing silence [00000393] main audio output debug: audio

Easier way to reproduce: 1.) Start playing a video on http://www.stage6.com 2.) Close the tab in which it is playing, and it crashes
Did you report this upstream? I'm not the developer, so there's not much I can help you with. It also appears that stage6 has been shut down. :( Sorry!
