Coincidentally, I have been working on a similar Chrome/Opera extension. It works for Google, Yahoo!, Bing, DuckDuckGo and a few others, but I haven't finished it or packaged it up to submit to Google yet. Some rough edges and lots of TODOs still. Anyway, it's here if anyone is interested in the code or would like to collaborate: https://github.com/daverayment/SearchHide https://github.com/daverayment/SearchHide
