Despite this being release for Karagarga (amazing place) users shouldn't think that membership there has anything to do with this addon, sure one of the links points to KG but it's really a much more open and multi-site script that allows you to go from IMDB to pretty much any site you desire (you can edit yourself the code to include more search engines).

Instead of having to see a movie on imdb then go to the other site and click the search link, then type/paste the movie title and possibly the year to director too (depending on how good the site's search is), you instead click the favicon representing that site and voila.
