Yeeeeeesssss! Simple and effective just the way I like it. So convenient to find information in forum threads and tech sites, with a lot less button clicks than using the site's search button. I also use it to eliminate results on Amazon (with a - (minus) sign) because their search engine sucks.

I really like that I can choose where to search on the site too. We can do this on Google ourselves but this saves typing and button clicks. Thanks!

needs the simple ability to change search engine on the fly, instead of hiding it in options.
also would be nice to have it understand search engines already added into firefox.
