Duplication Killer Extension

If the url of tab you opened is the same as one you've already opened, close the new tab and activate the old one.
I recommend this for a person who opens too many tabs when one searches something.

既に開いているタブのURLと同じものを別のタブで開こうとすると、それをキャンセルしてもともと開いていたタブをアクティブにします。
調べ物をしているとタブの収集がつかなくなる人におすすめ。
