Description

Tab Deduper is an extension to find and remove duplicate Chrome tabs. Unlike other currently available extensions which dedup tabs, Tab Deduper differentiates itself in the following ways: - Duplicate tabs are not automatically closed. A list of duplicated tabs are presented, allowing for precise control over which tab gets closed. - Use of text OR regular expression based settings to control how tabs are compared, including use of title, fragment, and doing sed-like regex replacements on URLs. This last feature is very useful if you use other extensions which modify your tab URLs.

It seems to (??? no proof) find duplicate tabs. OK. Then what? It displays them in a long vertical list using all sorts of colors painting a tiny bar to the left of them. No "select". No "remove dups". No nothing, no sense. Much effort with zero functionality and zero effect.

Crashes my chrome with a lot of tabs and windows. Had to disable the extension again
