How do I prevent flash videos from automatically playing?

more options

Whenever I open a new link to youtube, collegehumor, various tv websites, etc. firefox always automatically starts playing the video even before i even look at that tab. Sometimes when firefox freezes I have a few video tabs open and when it starts back up, a few videos start playing at once.

Is there a way to turn this off? I'd like to manually control when these videos play.

Using Flashblock solves that.
