Description from store
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
# create event - Close repeated tabs when a new tab is created, more details in tabs.onCreated.addListener
# remove event - Close repeated tabs when a tab is closed, more details in tabs.onRemoved.addListener
# replace event - Close repeated tabs when a tab is replaced with another tab due to prerendering or instant, more details in tabs.onReplaced.addListener
There are also two other events that can be disabled or reactivated that are specific to the extension/add-on:
# start event - Close repeated tabs when your browser is launched
# datachange event - Close repeated tabs when you change Sort order, Events, URLs and Others configurations from extension

- (2024-10-03) 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.
- (2024-09-17) John Weiss: 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.

- (2023-09-17) Sam Jones: Would be perfect if it automatically closed chrome://newtab pages also. For some reason it doesn't detect this as a duplicate
