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:

<ul>
<li>Start event - Close repeated tabs when your browser is launched</li>
<li>Update event - Close repeated tabs when a tab is updated, more details in tabs.onUpdated.addListener</li>
<li>Create event - Close repeated tabs when a new tab is created, more details in tabs.onCreated.addListener</li>
<li>Replace event - Close repeated tabs when a tab is replaced with another tab due to prerendering or instant, more details in tabs.onReplaced.addListener</li>
<li>Attach event - Close repeated tabs when a tab is attached to another window or detached (creating a new window), more details in tabs.onAttached.addListener</li>
<li>Datachange event - Close repeated tabs when you change "sort order", "URLs", "others" and "events" configurations from extension</li>
</ul>

Hi please can you support it again? I can't install it and its a great extension :(
Kerry Johnson
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.

one of the best tools. the toolbar icons could be more intuitive need a one-click-switch option

Would be perfect if it automatically closed chrome://newtab pages also. For some reason it doesn't detect this as a duplicate

Could be great, if it would also prevent chrome to open duplicate tab when an (existing) URL is entered in command line of windows.

For some reason, this is better & has more options than the first result on Google :| I really love all the options & interface (especially the smiling icon)!

Works flawlessly. By default, it doesn't close duplicate tabs in different windows, which I want, but it's very easy to change that in the options.
