A flashblock tool that provides more control over Flash content.
FlashControl prevents Flash content from loading unless you allow it.
With FlashControl installed, web content that requires Flash plugins will be disabled by default. You then enable content by clicking on a blocked area on any given webpage, or via FlashControl's address bar icon. You can reblock the content that you've unblocked as well.
This can help reduce CPU load, and moreover provide some security control so that content isn't automatically loaded without your permission.
