Rated 5 out of 5 stars

Until KartOO shut down in late January 2010, it was the best search engine--actually meta-search engine--available in the English language and possibly the world. The French search tool gave highly relevant results and used an advanced graphical interface that incorporated thumbnails of the resulting websites, which made sorting through the results a swift and painless process. Google's search engine was stone-age in comparison. As for the KartOO Firefox add-on, I used it for a several months and encountered no problems.
