Just one Search Engine?? Rated 2 out of 5 stars

I want to find an extension / plugin that allows me to mouse over or highlight (text, image, graphic) and search a choice of engines: Google, Gmaps, Froogle, Amazon, eBay, IMDB, Urban Dictionary, GImages, etc. It would be sweet if I could just use the list of engines I've added to Firefox's search-bar-box as I can in Firefox with "Context Search" plugin!

Until then this is a rather limited application.
