Hello, Sometimes when I move the mouse over a flash video to pause it or to even start it, my computer completely freezes. I'm using a laptop and the LED that lights up whenever the HD is being used completely stops lighting, indicating that the hard drive is no longer being used. All buttons stop working, including combinations like CTRL + ALT + Delete. The Caps Lock LED does not light up when pressing Caps Lock, and my mouse completely stops moving. All I'm left up is with a frozen image, and the only way to stop the computer is by pressing and holding the stop button on the laptop. When I restart the computer, the websites and tabs restore on the next Firefox start-up. I thought this only happened to YouTube videos, but now I've experienced it with another type of video. This only happens in Firefox and with flash videos. Does anybody know how I can fix this? Thanks!
