Close tabs which are duplicated. Only tabs with exact URL matches are closed.

Image from store Close Duplicate Tab
Description from store Ever run into situations where you have lots of tabs open and you realize you have some of them open multiple times? If then you felt the need to close duplicate instances of that tab, help is at hand! Close Duplicate Tab does exactly what its name says - it identifies URLs which are open in multiple tabs, and closes all instances retaining one. It also is smart enough to detect if you are on one of those duplicate tabs, and closes the other ones so you can continue doing what you are. Coming soon: keyboard shortcut, auto close, limit to current window, group top domains in single window etc. Suggest more features! v2.5 * NEW: Top domains listed on hovering over the extension icon. v2.4 * Pinned tabs will no longer be closed if they are duplicates. v2.3 * Now see titles for duplicate tabs, not long URLs * Special case handling for websites that "replace" tabs behind the scenes. Short version: more accurate duplicate tracking. v2.2 * Bug fix to handle browser restarts v2.0 ## MAJOR Upgrade!!! * Options page, with list of upcoming capabilties * NEW: Reorder (sort) pages by URL v1.8: * Lists open tab count, and duplicate tab count * List duplicate URLs, and their counts * Groundwork for options (coming soon!) v1.6: * Now identifies & closes duplicates across windows * More accessible colors for duplicate count badge

  • (2023-10-21) Hang Yin: Super! One click for exactly what I want!
  • (2023-09-05) Francesco Amendola: Awesome extention! It would be great if it had also a key binding to run it.
  • (2023-05-31) Delta Squared: I like the simplicity of this. I have made a key binding in chrome settings to activate the extension with ctrl-alt-x. I just wish there was an option for it to only work with the current window instead of globally.
  • (2023-01-13) George Quan: A handy tool - wish it could allow for the selection of DOMAINS rather than exact url strings. Otherwise works great.
  • (2022-11-21) Yeh Yeh: Hi Really love your extension However I do found that the duplication may not work well for "group-tab" Looking forward for more features/control Thanks Yeh
  • (2022-10-25) 윌로우: too simple
  • (2022-05-11) Al F: I just thought of this idea and wanted to develop this extension as coding practice, but checked and saw you already beat me to it. It's works exactly how I envisioned it, thanks.
  • (2022-04-18) cruukz: It was the best tool to close duplicate tabs. Thank you!
  • (2022-03-29) Josh Bouganim: simple and works great
  • (2021-11-12) Tolga Varol: Closes the duplicate tabs, does the job well. As well reading through the reviews here, developer is very involved with her/his work.
  • (2021-03-26) Artemi Lebedev: Works well only closes all with one click
  • (2020-10-06) paulo guedes: extremely useful, runs neatly and works exactly as expected. eager for the new features.
  • (2020-04-05) Ahmet C. Ay: The only problem is the badge is broken because it uses the function "chrome.runtime.onInstalled.addListener" which means it will only work properly after the first install or after an update. It will stop working once you close the browser and open it back up again. For that you need "chrome.runtime.onStartup.addListener".
  • (2020-03-23) Oleg Ivanov: After the recent update it now closes duplicates across all chrome windows instead of closing duplicates in the current one only. This is so frustrating for me :( Could you, please, add an option to control this behavior? Global/current window
  • (2020-03-23) yu byeonggeon: nice update
  • (2020-02-26) 唯一的缺点是无法提示
  • (2020-02-18) ANRK ALT: works perfectly.
  • (2019-10-20) Александр Хан: This extension work better https://chrome.google.com/webstore/detail/duplicate-tabs-closer/hleiiepnagionbolbhmligmnidmaehoo
  • (2019-06-16) Stephen S: Good little utility. One click and done when the icon lights up green. That's nice as it's not too in your face.
  • (2019-03-31) Paul Dowsett: Good, but why the large file size?
  • (2019-01-15) Bazsi Sün: Eddig jó volt de most pl a chromium alapú awast security browser-ben nem működik...
  • (2018-09-20) Saroj Khatiwada: In the latest google chrome (v 69.xxx) with material theme, the icon looks bland with no coloring at all; just plain gray. There is no indication of duplicate tabs whatsoever. Please test and adjust. Thanks.
  • (2018-07-27) g.n .v: works
  • (2018-07-26) Justin Cram: Rather large in file size to do such simple functions it does which makes me not trust the app. Disabled for now.
  • (2018-06-25) Michael Ryan: The badge color is absolutely horrible. White text on a bright lime green background?!? You might as well make it white-on-yellow or white-on-white, and it would be as useful. Also, the duplicate count seems to be wrong most of the time. And the badge shows the same number in all windows, even those without duplicates. Clicking the button in a window with duplicates will remove duplicates in that window and clear the badge count in all windows, even though other windows still have duplicates. This extension needs to be tested more.
  • (2018-01-08) esgalmir: на хроме это лучшее
  • (2018-01-01) N D: very useful when have hundred tabs open - thanks alot
  • (2017-09-05) Jarkko S. Hakala: I have seen better, just didn't find it today. The better one shows the url of duplicates when mouse-over, and counter is more visible for color blind(that is, it has contrast).
  • (2017-04-23) Óscar: Just closes the current window duplicates.
  • (2017-04-05) Josh Diaz: It does what it says, however, I'd like for it to have the option of automatically closing any duplicate tab as soon it detects it. Also the "options" menu item is disabled
  • (2016-06-14) Tintumon M: What I need is working fine. But need to improve in: It take duplicates count from all windows. But closes duplicate tabs only from single window. So, it shows wrong count. And give priority for pinned tab. Don't close if any duplicate tab in pinned tabs.Instead of current tab, it closes the duplicate pinned tab
  • (2016-04-12) Thomago: Would actually use it if it wasn't for the fact that every now and then it shows a duplicate tab even though only one Chrome window with only one tab is open.
  • (2016-03-09) Bruce Deuce: Does not close duplicate tabs - closes random(?) tab instead. BOOOOOO!
  • (2016-02-03) Alon Lavi: Great! However, I'd really love to have an option to see a list of the duplicated tabs before closing them. Do that and I'll give you 5! ;) I can help if needed.
  • (2015-12-13) Francesco Servilio: Very useful. However, sometimes it states there are duplicate tabs (the counter tells 1 or 2), but there are not; and if I click the button to close those tabs, it doesn't close anything (as there is nothing to close) and the counter does not reset.
  • (2015-11-23) Yaru Uvva: duplicates count shows 2 although there is no duplicate tabs
  • (2015-08-03) Exactly what I had in mind: • It lights up if there are any duplicates • It closes them in one click Unfortunately the duplicates count is always incorrect :(

  • (2023-11-30, v:2.5) Filippo Ardito: feature request: ignore hash in URL as different
    In my case (eg using Gitlab) I end up often with tabs that are different just by section, which is a hash in the URL, eg https://my.domain.com/issues/350#note_824 https://my.domain.com/issues/350 Currently this extension (useful!) wants an exact match, but the above for me would are qualify. This could be a preference setting
  • (2023-10-23, v:2.5) Preksha Jain: Duplicates and folders
    It would be great if the tab reordering didn't delete all of my tab groups. I sort my action items and by clicking the extension. all my tabs are moved out of my groupsand all my folders are deleted.
  • (2023-03-21, v:2.5) Joshua Furgason: There is no privacy information with this extension
    What data does this extension use and who is it shared with and why?
  • (2022-11-22, v:2.5) Ben Ferber: Data Collection Practices
    1. Aside from browsing history, what data is collected from the user by this extension? 2. Do you send any information to third party services/providers? 3. Is browsing history utilized for any purposes (other than the local function to close tabs)?
  • (2021-12-07, v:2.5) Rainbow Warrior Princess: BUG: Sometimes extension icon doesn't turn yellow when tab duplicates are there
    I noticed that sometimes when there are tab duplicates, the extension icon doesn't turn yellow, yet when clicking on the icon it closes the tab duplicates.
  • (2021-03-30, v:2.5) Ricardo M: Edge run-as-app detected as duplicate
    on Chrome, I run the Google Calendar as an app in a window by itself and it works fine. On Edge, I run Google Calendar as an app, but your extension detects it as a duplicate, so when I click to close duplicates, it closes the Google Calendar that I use as an app. On Edge to do this you go to the 3-dots menu ► Apps ► "install this site as an app". Could you please have a look into this? I was hoping your extension would have an Ignore List where I could add Google Calendar's URL for your extension to ignore but looks like this isn't available.
  • (2020-12-26, v:2.5) Jiri Pik: Do not sort PINNED tabs
    I love the extension. Would it be please possible not to re-order the pinned tabs?
  • (2020-08-30, v:2.5) Shinebayar Gansukh: Do you have firefox version?
    Hi, this is my favorite extension on chrome. Do you have firefox version?
  • (2020-05-02, v:2.4) Travis Chen: Incorrectly Identified Tabs as Duplicates
    The following two URLs are considered as duplicates, even though they are not: https://mail.google.com/mail/u/0/#inbox https://mail.google.com/mail/u/2/#inbox My guess is that the extension is using some sort of hashing algorithm instead of directly comparing the strings?
  • (2020-04-29, v:2.4) Jean du Plessis: Add option to ignore URL hash when matching duplicates
    Google docs for example changes the URL hash based on where your focus in the document. However I often end up with 2-3 copies of the same document open but with different URLs based on where each one might be focused in the document. I'd really like to be able to have them picked up as a duplicate.
  • (2019-12-14, v:1.5) Stephen S: Delete the non pinned version of the tab
    Lets say, there are two tabs the same URL and one is pinned and the other not. It would be nice to close this non pinned tab and keep the pinned one. Currently this doesn't recognise this and doesn't close either one.
  • (2018-05-30, v:1.5) XEO XTH: Please fix the tab counter
    Tab counter disappears when restart chrome.
  • (2017-07-19, v:1.5) N D: should put website for donations
    should put website to enable donations
  • (2017-06-12, v:1.5) titusfx: The counting is wrong
    The count of duplicate tabs is wrong, and Im only using one windows. BT, Thanks for the extension.
  • (2017-05-07, v:1.5) Ahmet C. Ay: Counter disappears
    Tab counter disappears, disabling and enabling back doesn't fix it. I had to uninstall and reinstall it.
  • (2017-04-07, v:1.5) Close tabs duplicate automaticly
    Is the new function 'Close tabs duplicate automaticly' already available?
  • (2016-07-14, v:1.5) Firuz Juraev: Проблемы с иконками / Problems with icons
