Inquisitor was originally built as a plug-in for the Apple Safari browser.  Now it’s available for the Firefox and IE browsers as well.  Inquisitor adds a drop-down box to the Firefox search box where it does word completion, tracking of your search history as well as easy access to Flickr and Wikipedia searches.  It also shows you how often you’ve been at sites you’ve already searched. Inquisitor is a must-have plug-in for speeding up and shaping your searches. The modest downside is that when you install Inquisitor, it changes your search engine to Yahoo, not surprisingly since the software is owned by Yahoo!  Your search engine can easily be changed back to Google in the plug-in’s preferences.
