You can set individual sites to accept Flash or not.
Or you can do what I did, which is to leave it in what I believe is the Click to Flash default setting - no flash site works unless you make the choice to use Flash.
When I come to a site that wants Flash I see a window displaying the word Flash. If I choose to watch, I click on the window and Flash is enabled. Otherwise I simply move on.
