Obsessed with google

Most of us turn to Google if we need to make a web search for any information that we want .No complains cos Google gives us the best results and we know it.But that doesnt mean searching in Yahoo,live and ask who have improved their search technology too and sometimes u never know that u might find something u lookin for in a search engine other Google.
A firefox user that i am use this extension called customizegoogle
what this extension does is gives u option to search the same search-text on yahoo,Live , ask and other major search engines by clicking a link.
Also check out this greasemonkey script which even does a better job the difference being it works on all search sites whereas the customizegoogle extension only on google search.
