How do I enable Click to Play in Mozilla Firefox?

Firefox versions 8 and above support Click to Play (also known as Click to Activate) functionality for browser plugins. 

By enabling Click to Play, web content that requires plugins such as Java, Flash, Silverlight, Adobe Reader, QuickTime, and more will be disabled by default. Users must manually Click to Play plugin content on any given web page in order for the content to load. This provides a useful security control, so that malicious content is not automatically executed by the browser.
