Exceptional extension, full of options. It can check the container of each tab, if wanted, so there's no risk of closing tabs with the same URL, but with different credentials. It can search for duplicates in different windows. It lists the duplicates in a pop-up dialogue, so individual tabs may be closed.
It has an option to compare titles, instead of URL, which is not so useful (instead, it could compare both URL plus title for a match, skipping some Pages which use cookies, local storage and other data bases to manage states, without relying on URL...)
