Disabling Flash on Specific Sites?

xrjlx asks: "Does anyone know how to disable flash on just specific sites like cnet and yahoo so that those annoying ads don't come up on the screen. One way to do it is by setting "run active x controls" to "prompt." This gets annoying though because many sites legitimately use them. Are there any programs written that will allow me to just selectively block the use of flash on certain sites?" It makes sense to me that, like cookies and the use of Javascript, ALL browsers should have some kind of by-domain filter that selectively activates whatever set of plugins (including Flash) that provides the user with the kind of web experience that they want, of course, many might see this as too much micromanagement for their tastes. I say it all boils down to a well defined UI. What say you?
