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.
