ClickToFlash is a WebKit plug-in that prevents automatic loading of Adobe Flash content. If you want to see the content, you can opt-in by clicking on it or adding an entire site to its whitelist.
Try control-clicking (or right-clicking) on a unloaded Flash box to access ClickToFlash's contextual menu which allow you to do advanced things like edit its whitelist.
