I stand corrected. You CAN search with 1 click if you deselect all but one engine. 5 stars.

I like it

多数の画像検索サイトから選んで、もしくはまとめて検索できる。画面キャプチャモードも搭載。

Good addon, but the thing I don't like is that it has only the normal search, as when I go in Google and I select "image" for a word or an expression. It doesn't have similar images search, and it's the most useful feature. Capture and search is the most brilliant thing. I can select an area with my mouse, and doing searches on it!
