When using Internet Explorer, and I go to a Youtube video, the video starts playing as soon as IE opens that page. But with Firefox, when I go to a Youtube video, the video does not start; instead, I get the blank box with the right-pointing triangle prompting me to click it to start the video. When I do, the video goes ahead and start. Again, with IE, the video starts automatically but not with Firefox. Thank you.

I had my cousin, in another state, another computer of course, if he had that problem with Firefox, and he said no, that the videos autostart. So, that implies it is some setting with Firefox.
