Editors' ReviewDownload.com staffSeptember 18, 2007Most add-ons throw in some type of search functionality, but few bring extra value to the table. This discreet Internet Explorer plug-in, however, truly helps expand or narrow Web searches.Xippee is an unobtrusive add-on--it doesn't appear as a toolbar button or new toolbar. Instead it pops up a small panel when you double-click on text in a list of search results--the text blurb with the link, not the link itself. The panel includes a Plus button and a Minus button. Clicking one will either add or remove results that are similar to the one you selected.This free plug-in for IE performed very well in our tests, responding to our clicks quickly. We liked that Xippees plus and minus panel popped up even while we had our pop-up blocker enabled. Users won't have to worry about opening up their surfing experience to annoying pop-up ads while enjoying Xippees features. We recommend it for anyone using IE for browsing.
