So in the last couple days ive had this happen a few times. an animated image on a page, not a Flash one just a png or gif or something, would stop moving and the browser would become unresponsive. And then that image would start flashing green rapidly. after a while of this the entire browser would crash. The errors it gives me are the standard ones for generic "There was a problem" crashes. Also the plugin container would crash too. The green color was interesting, because ive seen it before. Its the same green color that would show up if I combined multiple video files into one using DOS, for a brief moment between when one clip ended and the next began. I did try to refresh firefox after this happened the first time. Refresh went through, but didnt solve the problem.
