Mozilla is changing the way Firefox loads third party plugins such as Flash, Java and Silverlight. This change will help increase Firefox performance and stability, and provide significant security benefits, while at the same time providing more control over plugins to our users.
Previously Firefox would automatically load any plugin requested by a website. Leveraging Click to Play Firefox will only load plugins when a user takes the action of clicking to make a particular plugin play or the user has previously configured Click To Play to always run plugins on the particular website.Firefox Announces User Plugin Control For Greater Stability and Security [blog.mozilla.org]
Click to Play allows users to easily choose if they wish to run a plugin on a particular site. Users can also configure sites to never run plugins or conversely always run plugins. This change puts the user in control. By only activating plugins that the user desires to load, we’re helping eliminate pauses, crashes and other consequences of unwanted plugins.
