Prevent Duplicate Tabs

Prevent duplicate tabs
What is Prevent Duplicate Tabs?
"Prevent Duplicate Tabs" is an Edge add-on that stops the browser from creating or repeating duplicate tabs of the same addresses. This extension allows you to manage which events trigger the closing of repeated tabs and whether or not querystrings and hashes in URLs are considering factors. It provides an option to specify exceptions and effectively works in both normal and incognito modes. The process is automatic, but it provides quick enable/disable options for user flexibility.

Add-on 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

The default option is that it closes existing tabs which means you loose input data you have made in a existing tab to get a new tab. Does not make sense. If you disable that, it prevents opening another tab, but it does not jump to the existing tab. So with many tabs, you only know it is already opened but not where and have to jump manually again.

3 star so far, even though looks great. Here is the thing: So far as testing, it requires a new tab to be totally loaded and then it closed the "other" duplicates. Can there be a feature where it simply knows which tabs are there and take your focus to the tab in question? I have a lot of tabs situated across windows and don't really want to hunt or change the window of docus for my tabs.
