It's somewhat hard to describe KwiClick in just a few words. KwiClick is a Firefox plugin that combines a number of seemingly unconnected functions in one. Among other things, it allows you to quickly perform searches by highlighting and right-clicking on any word in Firefox, and the results are displayed in a dedicated pop-up window, so that you don't have to actually browse to Google or Yahoo to see your search results. But at the same time, it also integrates with YouTube and other video services, so that you can play videos in the KwiClick pop-up window while you continue to browse the web.
