Summary
Prevents from automatically creating new tabs or repeating tabs when two or more tabs have the same addresses
The process of closing repeated tabs is automatic based on 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 does not close repeated tabs.
The extension/add-on has support for closing repeated tabs in incognito/anonymous mode, but this works in isolation and will not share any information in anonymous mode with normal mode, being completely separate actions.
Among the configurations you can choose to consider or disregard querystring and hashes in URLs as a factor to differentiate them.
It is also possible to configure whether you prefer to close the oldest tabs and whether you want to prevent the active tab (currently visible) from being closed.
The closing of the tabs works based on events from the Chrome API and you can disable or reactivate such events within the extension/add-on:
update event - Close repeated tabs when a tab is updated, more details in tabs.onUpdated.addListener
