Works so sell that,
when I swithed to another pc, and the dup tabs won't close after pressing the shortcut key,
it took me quite long to realize that i havent installed this extension on new pc yet.

Works great. I really like the "Filters" options - without them the extension would be pretty much useless to me.

Absolutely beautiful. Exactly what I wanted. Automatically closing older duplicate tabs when a new duplicate is opened should be a stock option in firefox.

Simple, yet effective.
