This extension will allow you to close duplicates of the same page
No Duplicates helps you manage your tabs so you don't end up with dozens of duplicate tabs.
No Duplicates will warn you when you open "Yet another tab" of a page you already have open. You can choose to close the others and keep this one open; close all and go to one; ... or just ignore it and have duplicated tabs :)
- Added a means to pause the extension
- Shortened the notification questions
