Chrome offers a “click-to-play” feature for all plug-ins

Works just like ClickToFlash for Safari by disabling a plug-in until the user clicks it, except it does this for all plug-ins (Quicktime, Windows Media, Real (LOL!)). You can whitelist sites you like.

In a quick test, it seemed a little slow to me and there’s no right-click enabled to immediately add the current site to your whitelist. Still, I love this approach to sandboxing plug-ins being built right in.
