When blocking ads with your hostfile, you sometimes encounter empty IFrames, which in addition to being ugly, make scrolling jerky and distracting in IE. This was almost the entire inspiration for the “Hide Anything” browser extension. Now, a better alternative: the Hide IFrames bookmarklet (DOM-capable browser required).

If none of the above made sense, scroll on down, and remember that you are neither a better nor worse person for it.
