Note: According to the developer, ClickToFlash has reached the end of its development cycle: "Due to Apple’s new development policies, version 3.2 is the final version of ClickToPlugin." (This also applies to ClickToFlash.)
ClickToFlash is a highly customizable extension that prevents Safari from launching the Flash plug-in automatically.
It replaces every Flash object by an unobtrusive placeholder that can be clicked to load the Flash content, and it can replace many Flash-based media players by Safari's native HTML5 media player.
