Firefox keyword searches are the way to go - you can setup URLs with arbitrary %s variables and go directly to the results page for a given tool. I have one or two char shortcuts for my most commonly used tools setup and my productivity exploded. With bookmarklets you can embed JavaScript and do things like implement parameters or loop through lists of search terms with each term opening a new tab. Seriously one of the most underrated tools available for anyone that has to use web tools all day.
