Just noticed this feature in Firefox this morning which is a real time saver. I’m often looking around for books and I have a couple of favourite websites (Amazon, Readings). In Firefox you can assign a search box on say your Amazon website to a keyword. Then whenever you want to make a search you just type that keyword followed by your search string into the place where you would normally type a web address and hit return. And viola, the search results appear.

Here is the link to the Firefox help page that describes how to do it.
