ClickToPlugin 2.5.5 - Prevents Safari from launching plugins automatically.. (Free): "ClickToPlugin is a highly customizable extension that prevents Safari from launching plug-ins automatically, resulting in faster browsing, reduced fan usage, and increased battery life. It replaces every plug-in object by an unobtrusive placeholder that can be clicked to load the embedded content. Further, it can replace many plug-in-based media players by Safari's native HTML5 media player.
