"This script doesn't completely block Flash elements in a page. Rather it "hides" them and substitutes a "button" that you may "press" to make individual Flash elements visible if you like. It's simple, quick, and much less sophisticated than FlashBlock. For most folks, this does most of the job they want done most of the time: it stops noxious, moving, distracting flash ads while letting you choose to see useful flash content." - ovigia from Bookmarklet
