Did you know that flash invariably slows down the loading of a web site? Not only that, it is a perfect hide-out for malicious code that can creep into your browser/system and wreak havoc. Flash block, as the name suggests, is an Internet Security Plug-in that can help you to block any flash files playing while you browse the Internet. However, it does have enough flexibility to allow you to view flash when you have to (or when you want to) just by clicking on a button. It presently blocks all Macromedia Flash files -- Flash, Shockwave and Authorwave.
