Grande... era una delle poche cose che mi mancano da Firefox... e ora posso installarlo su IE... 
Inline Search from IE Forge is a must have utility for Internet Explorer. It gives new FireFox-like inline search UI to IE and does find as you type. Find has also been a feature I haven't liked in IE. I can never figure out what it highlighted on the page! And the modal UI is annoying.
