Autor: NC, 6 lat temuUPDATE (2026-06-28):
Awesome to see the developer is actively maintaining this add-on project and has implemented a lot of the features I requested all those years ago! Their response made me add this extension again, seeing as I have been running into the same 'too many tabs' problems as years ago.
Point 1: Appreciate that tip!
Point 2: The open popup on duplicate detected seems to be buggy on my setup, popping up randomly on pages that have been open, and not always loading on some other pages. Will have to skip using that for now.
Point 3: I think this point still stands, in practice, even though I see there is that option in theory. It's nice to know I can tell which of the tabs listed are new or old based on how they are displayed as compared to the setting I have in place, although I am not sure that is super intuitive to new users of the add-on. I wish there was a way to note the window each Tab is in, to be more informed with making dynamic decisions as we use the browser. Sometimes it makes sense to keep the newer tabs because they are more relevant when tied to the current tab stack we're browsing on. But sometimes it is more useful to keep the old instead of loading yet another duplicate tab, for instance when u open a duplicate in the same browsing session.
Either way the add-on feels much better than I remember it being 6 years ago, so I am upgrading my rating to the 5 stars it deserves.

ORIGINAL (2020-11-26):
This Extension is nearly perfect! The best of the duplicate tab closing extensions on Firefox. I would love to see a couple features that I think would push this into the perfect 5* range.
[1] Whitelist should be available with the 'do nothing' option so that it applies to the "Close All" button as well, so that I can exclude certain pages (such as New Tab or about:blank) but still use that option.
[2] Add the option to pop up a Notification on duplicate. Automatically removing tabs has caused me issues, so I do not use that feature, but I still would love an option to know when I am duplicating an existing tab in the moment.
[3] In the duplicate tab notification window it would be nice to have the options to close New or Old duplicated tab, or to do nothing.
Thanks for all the hard work!

Data: miesiąc temuOn point 1: this is already available in v4.2.0. The hide-whitelisted button in the duplicate tabs footer makes the "Close duplicates" button skip whitelisted tabs, regardless of whether auto-close is on or off. New Tab and about:blank pages are also excluded from detection entirely, so they will never appear in the list or be affected by "Close duplicates".
On point 2 (notification on duplicate): the "Open popup on duplicate detected" option in the Options page already does this. When enabled, the popup opens automatically each time a new duplicate is detected, so you are immediately aware without any automatic closing.
On point 3 (choose new/old/nothing per duplicate): when the popup opens automatically (see point 2), you can see exactly which tabs are duplicates and use the X button next to any row to close whichever one you want. The global default for which tab is kept is also configurable via the Priority settings ("Keep older tab" / "Keep newer tab").

- Ocena: 5/5Autor: kartis56, 2 miesiące temu4.1.5に更新した所、保存したセッションを開いて、さらに同一タブを開いたときに重複を検知できなくなった。
4.2.1 で治ってることを確認した。修正お疲れ様ですOdpowiedź autora
Data: miesiąc temuThank you for the report!
I was unable to reproduce the issue on my end, but a fix for a related race condition was included in v4.2.0.
Could you please test with v4.2.0 and let me know if the problem is resolved?
If you can still reproduce it, it would really help to know:
What you mean by "saved session" (Firefox built-in session restore, or a session manager extension such as Tab Session Manager?)
Which mode you are using: auto-close or notify only
Your Firefox version
The exact steps to reproduce
Also, if possible, could you open a GitHub issue? It makes it much easier to track and follow up: https://github.com/Peuj/duplicate-tabs-closer/issues
Thanks again! - Ocena: 5/5Autor: B Tang, 2 miesiące temuWorks really well. You can configure it to ignore certain parts of the URL like after the search (?) part or hash (#) part of the URL as some sites will generate duplicate tabs with these parts different.

when I swithed to another pc, and the dup tabs won't close after pressing the shortcut key,
it took me quite long to realize that i havent installed this extension on new pc yet. - Ocena: 5/5Autor: たやまみ, 10 miesięcy temu

- Ocena: 5/5Autor: Kachajal, 2 lata temuAbsolutely beautiful. Exactly what I wanted. Automatically closing older duplicate tabs when a new duplicate is opened should be a stock option in firefox.

Drawback: the add-on seems to have been abandoned 4 years ago, as seen on Github:
https://github.com/Peuj/duplicate-tabs-closer
But I find a bug:
Whatever your choice in "Priority" parameter in the Options, the add-on always keeps the oldest visited tab. This parameter seems to not work at all.
And I also have two little requests:
- First one: it would be nice not to include the tabs "New tab" in the list.
- And second one: it would be nice to disregard (ignore) a final "/".
Both requests could have their checkbox in the Option page (with On by default).
But I don't know what to think, given that the developments seem to have been abandoned 4 years ago.Odpowiedź autora
Data: miesiąc temuHi,
The extension was indeed quiet for a while, but development has resumed and v4.2.0 was just released today.
Priority bug: You are right, this was a real bug. The "Keep newer tab" option was not working correctly due to a comparison error with uninitialized timestamps. It is fixed in v4.2.0.
New Tab pages: These are already excluded from duplicate detection. Both about:newtab (Firefox) and chrome://newtab/ (Chrome) are treated as blank pages and ignored. They will not appear in the duplicate list.
Trailing slash: Also already handled. URLs are normalized before comparison and trailing slashes are always stripped, so https://example.com/ and https://example.com are treated as the same URL.
If you are still using the extension, updating to v4.2.0 should fix the priority issue. - Ocena: 5/5Autor: Adrian, 2 lata temu
- Ocena: 1/5Autor: Użytkownik Firefoksa 16024671, 2 lata temuWrite about my experience with this add-on? I wasted hours trying to figure out why I could have only one tab per domain. It didn't matter if the url was completely different. Utter POS because the PEUJ who designed it doesn't even know the meaning of "duplicate". IT MEANS "EXACTLY THE SAME", got that? Read again.

Data: miesiąc temuWhat you experienced is the result of the "Ignore path part in URL (domain only)" option being enabled in your settings. When that option is on, the extension considers any two tabs on the same domain as duplicates, regardless of the path. It is off by default.
Turning that option off in the Options page will restore the default behavior, where only tabs with identical URLs are considered duplicates.
If you are still using the extension, v4.2.0 was just released with a number of UI improvements, including a clearer duplicate tabs list that shows which tabs will be closed. - Ocena: 5/5Autor: akasico1, 3 lata temu

- Ocena: 4/5Autor: Reiner030, 3 lata temuSeems to work fine BUT ONLY IN ONE WINDOW ... I uses several windows and there are "no duplicates" found by this (and other) tab deduplication extension ...
Because of some somehow gone/lossed tabs I opened a saved session so I had to get rid of duplicated tabs.Odpowiedź autora
Data: miesiąc temuBy default, the extension only searches for duplicates within the currently focused window. To detect duplicates across all open windows, change the "Scope" setting to "All windows" in the Options page.
