Prevents automatic creation of new tabs or repeating tabs when two or more tabs have the same addresses

The process of closing repeated tabs is automatic based on the settings that you can determine within the extension/add-on, it is also possible to quickly disable and activate the add-on without having to access the extensions panel.

You can add a host or URL to specify as an exception so that the add-on doesn't close repeating tabs.

The extension/add-on has support for closing repeated tabs in incognito/incognito mode, but this works in isolation and will not share any information from incognito mode with normal mode, they are completely separate actions.

Among the settings you can choose to consider or disregard querystring and hashes in URLs as a factor to differentiate them.

It is also possible to configure if you prefer to close the oldest tabs and if you want to prevent the active tab (currently visible) from being closed.

Closing tabs works based on Chrome API events and you can disable or re-enable such events within the extension/add-on:

Mostly great, but "Preserve Active" does not work and I've lost some work duplicating active tab and it overtaking my current one. "Duplicate Tabs Closer" seems to work in this regard, otherwise I liked your extension.

The extension keeps causing me to lose work and time. Enabling "Preserve Active" and disablign "Close olders" doesn't work. My older tabs are getting closed.
