ClickToPlugin/ClickToFlash

ClickToPlugin is a lightweight and 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. ClickToFlash is a restriction of ClickToPlugin that only deals with Flash content. ClickToPlugin is currently localized in English, French, Spanish, Traditional Chinese, Simplified Chinese, and Japanese.
