I used YBOSS on a prototype of a firefox extension - https://addons.mozilla.org/en-US/firefox/addon/9986 https://addons.mozilla.org/en-US/firefox/addon/9986 It works ok, the main issues are: * the results are not as good as yahoo's real results * about 10% of the time the yahoo click-through url is incorrect (meaning instead of seeing the result you see a yahoo error page). I've since rewritten it to use Google's "AJAX" API (which is just JSON). Check out the flash section for how to get the JSON directly.
