Autoplay problems

Sorry, guys, but all of a sudden, I'm having autoplay problems.

It doesn't seem to be a problem with YouTube videos, but only with those from Comedy Central (from what I've seen so far, at least). The videos start automatically, even when I include code that's supposed to prevent that.

As you might have noticed, it's a particularly big problem when there are multiple videos on the same page. Then again, maybe it's only a problem with my particular browser (Firefox) or settings? I just don't know.

As I say, I've never had this happen before, and I haven't figured out how to fix it. Nothing I've tried so far has worked at all. So, my apologies if this has been a problem for you. I'm aware of it. But that's about all I can say.

Edit: OK, I fixed this at my end by going to the list of Firefox plugins and turning Shockwave Flash from "Always Activate" to "Ask to Activate." I don't know why this is necessary, all of a sudden, but it works. I just have to give permission for each video that I want to see.
